Create List View using SharePoint REST API

function createView(ListName, query )

{

var bodyContent = "{ '__metadata': { 'type': 'SP.View' }, 'Title': 'View Name', 'PersonalView': true, 'ViewQuery':'" + query + "' }";

var viewUrl = _spPageContextInfo.webAbsoluteUrl + "/_api/lists/getbytitle('"+ListName+"')/views"

 var executor;  executor = new SP.RequestExecutor(_spPageContextInfo.webAbsoluteUrl);  executor.executeAsync({ url: viewUrl,

method: "POST",

body: bodyContent,

headers: { 

"accept": "application/json;odata=verbose",

"content-type": "application/json;odata=verbose"

},

success: function (results) { alert("View Created.") },

error: function (error) { alert("Error in view creation.") }

});

}

Call this function you have to pass two parameter ListName and query.
ListName : This is name of list in which you want to create view.

Query : You have to pass CAML Query base on which filter is set and your view is created. Like

 '<Where><Eq><FieldRef Name=\"'Title'\" /><Value Type=\"Text\">' + TitleVar +'</Value></Eq</Where>';

You can customize your view but adding more attribute in body.

This code create a personal view because i set 'PersonalView' : true. If you want to create public view than set it to false. 

var bodyContent = "{ '__metadata': { 'type': 'SP.View' }, 'Title': 'View Name', 'PersonalView': true, 'ViewQuery':'" + query + "' }";

Sharepoint hide an item from edit control block (ECB)

A simpler way to remove any item from the Edit Control Block of SharePoint 2013 site is to add some javascript in master page. This way we can also hide the item(s) from specific lists. To do this, just add the below code in a javascript file and link that js file to your master page. Alternatively you can also make use of Content Editor Web part to embed it in a page.

$(document).ready(function ()

{

    $('.ms-core-menu-list').live('focus', function ()

    {

        var ecbToHide = "Version History";

        var showVersionHistory = $("li[text='" + ecbToHide + "']");

        if window.location.href.toLowerCase().indexOf(encodeURIComponent('/Lists/TechPerspect/')) != -1)

        {

            showVersionHistory.hide();

        }

        else

        {

            showVersionHistory.show();

        }

    });

});

The above snippet will remove the ECB item - "Version History" from the List - "TechPerspect".
