Finding SharePoint Item Level Permissions in ECMAScript

In EMAScript, to find out item level permissions in a list/library we don’t have respective

object in CurrentItem which states with Permission Name. Generally if we do the same in

 Server Object Model it returns Permission Names in string format. This ease our task but

in ECMAScript it returns in nvarchar format.

For Example, to know whether item has Read Permission, below is the snippet code.

if (ctx.CurrentItem.PermMask == "0xb008431061") { //This value is for Read Permission

}

else {

}

Alternative for Connectable Webparts [Filter SharePoint list with Partial Postback to page]

Problem:-

The other day, I wanted to filter a list view web part, triggered from some action in the same page.

Every time I do action, I wanted to automatically filter the sharepoint list with that value, without

doing a full postback/refreshing the page.

Solution

Generally as SharePoint developer will get an idea to develop a connectable webparts, but this is

difficult and takes time. The alternative is from SharePoint 2013, we have a new page added in

layouts folder inplview.aspx. This generates the "inplviewhash" tag when we do filtering/sorting and

mainly it appends with "#" in url. As we know when we have # url, the page doesn’t gets reload[postback].

For Example:- If we have two webparts in the Page containing one action performed and second

showing respective filtered data. The approach is when we do action in the above webpart through

javascript frame below way of url.

Function createFilterURL() {

var filterstring += //Frame query string which contains the formatted of filterfield1,filtervalue1 [if multiple values filterfields1,filtervalues1].

var wpqschema = ctx.View;

var querystring +=  '#InplviewHash' + wpqschema.slice(1, -1).toLowerCase() + '=' + filterstring ;

window.location.hash = querystring;

}

Sample URL Format is http://{sitecollection}/Lists/{ListName}/Default.aspx#InplviewHash{viewid}=FilterField1%3D{columnname}-FilterValue1%3D{columnvalue}
