Hii ni baada ya mwingine katika wangu inayoendelea mfululizo ya jinsi ya kutumia jQuery na SharePoint.
Kama unataka kujifunza zaidi kuhusu jQuery, Mimi sana kupendekeza: jQuery katika Action na kubeba Bibeault na Yehuda Katz.

Moja ya mambo ya kwanza nilidhani, mara moja Nilianza kucheza karibu na jQuery, was whether we could use it to secure a SharePoint view. The answer is “no” (au angalau, Mimi si wakidai inawezekana). Hata hivyo, it is certainly possible to make it difficult for people to see a particular view.

I started with my sandbox environment when working on this. I wrote about that environment here: Haraka na Easy: Kujenga jQuery yako mwenyewe Sandbox kwa SharePoint.

Na "kupata" maoni, kufuata hatua hizi:

1. Create a view you want to secure. I did that and called it “Secured View”.

   Hii ni nini inaonekana kama wakati ni si "kuulinda":

   

2. Kuongeza mhariri maudhui ya mtandao sehemu ya ukurasa mtazamo wa kutumia hila ilivyoelezwa katika makala Sandbox (i.e. kuongeza "PageView = Shared&ToolPaneView = 2 "ya URL).
3. Figure out your SharePoint _spUserId by following these crazy steps, amini au si:
   1. Kuingia katika SharePoint mazingira yako.
   2. Katika anuani ya shamba kivinjari cha, aina: "Javascript:tahadhari(_spUserId ").
   3. Kurekodi matokeo (ni "13" katika kesi yangu).

      

4. Kuongeza javascript zifuatazo CEWP yako katika mtazamo wa kanuni:
   
   

   <script     "text/javascript" src ="../../jQuery Library/jquery-1.3.2.min.js"> </script> <script aina ="text/javascript"> $(kazi() { tahadhari(_spUserId); var theSecuredView = $('Iframe[FilterLink * = Secured% 20View]'); kama ((theSecuredView.length > 0) && (_spUserId == 13)) $('Iframe[FilterLink * = Secured% 20View]').mzazi().mzazi().mzazi().html("<tr Bgcolor = nyekundu><td>Hakuna mtazamo kwa wewe!</td></tr>"); }); </script>

Nimekuwa pamoja na kwamba tahadhari(_spUserId) mstari katika huko kuonyesha jinsi hii si kweli "kupata" maoni, but simply making it more difficult to see. More on that in a moment.

Kimsingi, jQuery is looking for an iFrame on the page who has an attribute that contains “Secured View” in its value. Once it finds it, we check to see if the current user is “13”. If it is, sisi kutembea hadi DOM kwa <TR> tag (ambayo mimi figured nje na kuangalia chanzo na hazieleweki ni) na kisha kuchukua nafasi ya kwamba tag TR na ujumbe wangu. Mimi kwa kweli hawajui jinsi hii ni imara (Mimi nina mashaka sana, kwa kweli), but it worked in my sandbox. If I find a better way, Mimi itabidi blog juu yake. Hii ni matokeo:

Mimi bonyeza kifungo OK na data ni kubadilishwa na ujumbe kubwa nyekundu:

Kama unaweza kuwaambia, the way I’ve implement this “security” solution is to allow the web part to render itself. After it finishes, Mimi overwrite maudhui yake kwa mtazamo wangu "Hapana kwa wewe!"Ujumbe.

Pamoja na ukweli kwamba siyo kweli "kuulinda '" mtazamo, ni muhimu na uwezekano wa baadhi ya kazi na wajanja, it may eventually be securable in a more formal sense. The fundamental issue is that the client is getting all the data and then, tu baada ya anapata data, it wipes it out. If the client is getting the data, mtumiaji wajanja wanaweza kuzuia jQuery kutoka mbio wakati wote na kuona nini yeye / yeye anataka kuona.

There are other drawbacks. This “security” approach is based off a _spUserId. We’d want to really secure based on the full SharePoint security model, or at least by user name. That becomes progressively harder, lakini mimi kuona baadhi ya mambo mema imeandikwa juu ya somo hili, hivyo mimi nina matumaini kuna jibu nzuri na tatizo kwamba.

orodha ya maoni wenyewe lazima yachujwe, kama inawezekana. I haven’t tried to figure that out. I assume it’s possible, lakini si kweli kutatua kimsingi suala la usalama kwa sababu mtu bado anaweza tu aina URL ya maoni wanataka (kama walijua ni). Hata hivyo, trimming makes sense. It’s a good usability feature and it helps to obfuscate things. If an end user doesn’t know that the view event exists, they probably won’t try to use it. Wakati mwingine, kwamba nzuri ya kutosha.

Kwa bahati, Mimi itabidi zaidi ya kuandika juu ya mada hii baada ya muda.

Kama unataka kujifunza zaidi kuhusu jQuery, Mimi sana kupendekeza: jQuery katika Action na kubeba Bibeault na Yehuda Katz.

Hapo awali, I wrote about how to use jQuery to locate and hide a text field on a form. I didn’t care for the specific approach (Nilikuwa chaining wazazi - kwamba tu si kufanyika siku hizi, angalau katika familia ya ubora).

Wakati mimi kwanza kuanza kufikiri juu yake, Nilijua zinahitajika ili kupata <TR> ambayo mimi naweza kujificha waomba() njia. My early effort to find the correct <TR> ilikuwa kitu kama hii:

$('Tr:ina(pembejeo[title = Ficha Me!])');

tatizo na kwamba ni kwamba itakuwa kupata kila <TR> tag that had any parent relationship to the Hide Me! shamba, hata kama Ficha Me! ni Furushi ngazi nyingi kirefu katika <TR>’s. It turns out that on my sandbox form, kujieleza kwamba hupata 9 tofauti ya TR ambao Ficha Me! as a child somewhere in its DOM tree. I realized that I could walk back up the tree from the input field itself, hivyo kwamba ni jinsi gani mimi kuishia wazazi kutumia vibaya, lakini hawakuwa kukaa vizuri na mimi.

Mimi alitoa mawazo ya baadhi ya hii na moja ya mambo ya mimi kusoma hatimaye alifanya akili: Mimi naweza kutumia si() njia ya trim nje <TR>’s I don’t want in my wrapped set. Kwamba aliniongoza hii:

$('Tr:ina(pembejeo[title = Ficha Me!])').si('Tr:ina(tr)').kujificha();

kwanza kidogo anaona kila <TR> vitambulisho ambayo Ficha Me! field anywhere in their own hierarchy. It then strips out any <TR> kwamba pia mtoto <TR>. This leaves us with a single <TR> kwamba:

1) Hana <TR> mtoto kumbukumbu

2) Does have the input field as child.

Tunaweza kisha kuomba kujificha() njia ya kuweka kusababisha na sisi ni kosa.

Mimi bado kidogo neva kuhusu hili, lakini si kama neva kama wazazi chaining.

I don’t know if this is a best practice or not. There may be a more appropriate way of identifying just the <TR> that we care about in a SharePoint form. If you know, tafadhali post comment.

UPDATE (tayari!): Sikuweza kufikiri ya njia bora ya Machapisho <TR> tag nataka kujificha na aliandika juu yake hapa. You may still find this article interesting anyway so I’m leavnig it up.

Nataka kuficha Nakala shambani, "Ficha Me!"Kama inavyoonekana:

'

jQuery zifuatazo hana hila kwa ajili yangu:

<script aina ="text/javascript">

  $(kazi() {


    $('Pembejeo[title = Ficha Me!]').mzazi().mzazi().mzazi().kujificha();

  });

</script>

kanuni ni kusema, "Kupata mimi mashamba yote pembejeo ambao title = Ficha Me!. Kisha, kupata mzazi wake na kisha mzazi ijayo na * ijayo * mzazi (phew!) na waomba kujificha() njia juu ya jambo, chochote ni hutokea kwa kuwa.

I figured nje kwamba muundo mzazi na kuangalia HTML kwa fomu kuwa SharePoint umba kama inavyoonekana:

<TR>
    <TD nowrap="true" valign="top" upana="190px" darasani="ms-formlabel">
        <H3 darasani="ms-standardheader">
            <nobr>Kujificha Me!</nobr>
        </H3>
    </TD>

    <TD valign="top" darasani="ms-formbody" upana="400px">
        <!-- FieldName="Hide Me!"
                 FieldInternalName="Hide_x0020_Me_x0021_"
                 FieldType="SPFieldText"
        -->
        <span wewe="none">
            <pembejeo
                jina="ctl00$m$g_bdb23c2c_fde7_495f_8676_69714a308d8e$ctl00$ctl04$ctl02$ctl00$ctl00$ctl04$ctl00$ctl00$TextField"
                aina="text"
                maxlength="255"
                id="ctl00_m_g_bdb23c2c_fde7_495f_8676_69714a308d8e_ctl00_ctl04_ctl02_ctl00_ctl00_ctl04_ctl00_ctl00_TextField"
                cheo="Hide Me!"
                darasani="ms-long" />
                <br>
        </span>


    </TD>
</TR>

Hii picha inaonyesha huo, lakini alama juu na wazazi:

mzazi wa kwanza (1) is a span tag. Span’s parent (2) ni tag TD na kisha hatimaye sisi kupata mzazi halisi nataka kujificha (3) ambayo ni tag TR yenyewe.

This is a pretty terrible approach I think because it’s extremely dependent on the very specific structure of this form. When SharePoint 2010 hutoka nje, this whole structure could change and break this approach. What I really want to do is craft a jQuery selector that is along the lines of “find me all the TR’s (na tu TR vitambulisho) kwamba kuwa mahali fulani katika watoto wao mambo ya shamba pembejeo ambao title = Ficha Me!". I starting from the bottom and moving up. Assuming I figure this out, Mimi itabidi baada updated "haraka na rahisi 'baada ya.

Hii ni baada ya mwingine katika wangu inayoendelea mfululizo ya jinsi ya kutumia jQuery na SharePoint.
Kama unataka kujifunza zaidi kuhusu jQuery, Mimi sana kupendekeza: jQuery katika Action na kubeba Bibeault na Yehuda Katz.

Kupata ilianza na jQuery katika SharePoint ni ya kushangaza rahisi (kwangu). (I do have serious questions about a “best practices” approach to deploying these things to production, but that’s for another day). I’ve just started playing with this technology and to that end, I created a sandbox environment to use. If you’re looking to get started with jQuery, you may find this approach useful.

1. Create a Blank Site

Create a blank site somewhere in your site and call it something clever like “jQuery Sandbox”.

2. Download jQuery

You can download the jQuery javascript library from here: http://docs.jquery.com/Downloading_jQuery

Save that to to your desktop.

I have been using the “minified” version.

3. Create a SharePoint Document Library

In your sandbox site, create a document library.

4. Upload the jQuery Library to SharePoint

Access the doc library you just created and upload the jQuery library.

5. Create a Custom SharePoint List

I’ve started with a custom list because I want to muck about with standard SharePoint forms. You could also create a page in a pages library or web part pages and probably a lot of other places.

Add some columns to the custom list so that you have something to run jQuery against. My initial objectives were to:

1. Hide a field.
2. Assign a value to a field.

With that objective in mind, I added two text fields. Over time, I’ll be playing with links, images, lookups, nk.

6. Modify the NewForm.aspx Web Part Page and Add a Content Editor Web Part

This is a little black magic-ish , in that it’s a new concept to me. I first learned about this from Paulo Grenier, SharePoint jQuery Superstar, saa CodePlex yake tovuti ya mradi: http://spff.codeplex.com/.

Fuata hatua hizi ili kuongeza CEWP kwa ukurasa huo huo kwamba inaonyesha NewForm.aspx kwa orodha yoyote desturi:

1. Kupata orodha ya desturi na bonyeza Mpya.
2. Append zifuatazo URL: PageView = Shared&ToolPaneView = 2

Ambayo kubadilisha data yako boring vanilla kuingia fomu kutoka kwa kitu kama hiki:

Kwa hili:

Kuongeza mhariri maudhui ya mtandao sehemu ya ukurasa.

7. Kuandika jQuery wako kwanza Kanuni

Kufungua kwamba CEWP katika mtazamo wa kanuni na kuongeza yafuatayo:

Hapa ni kanuni halisi kama unataka nakala / kuweka:

<script
    "text/javascript"
    src ="../../jQuery Library/jquery-1.3.2.min.js">
</script>

<script aina ="text/javascript">
  $(kazi() {

    $('# ResultsID').html('Kuna' + $('A').ukubwa() + 'Vitambulisho vitambulisho kwenye ukurasa huu.');

  });
</script>

Kusababisha:
<div id ='ResultsID'></div>
/kusababisha

Note that the first <script> tag is referencing the actual jQuery library. Presumably, these things change over time, so you’ll want to make sure you a) use the right name and b) point it to the correct SharePoint document library.

Bask in the Glory

If you did it correctly, you’ll see a result similar to the following:

Wrapping Up

This isn’t the only way to get started, but it’s quick, easy and isolated from your existing SharePoint environment.
