Deletion using $batch on SharePoint (after sometime) , the browser is throwing Error, "Page become unresponsive"

Raju Yadav 1

I have a problem with my jQuery/Javascript code on a SharePoint webpart page. All works as expected but after some time the page becomes unresponsive throwing "This Page isn't responding" error in Edge (sometimes in Chrome)browser for jQuery. I am using a jQuery/javascript code on SharePoint Webpart page for deletion of 150 items at a time.

Please let me know what is the problem in the structure of the code given below:

//Deleting existing data items to SharePoint list using $batch

window.generateGUID = function () {
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
        var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
        return v.toString(16);
    });
}

function deleteListItems (spListName, data, goBackToParent) {
var queueNo = 1;
var totalQueue = Math.ceil(data.length / 150);

gettingRecords_ToDelete(queueNo);

function gettingRecords_ToDelete(page) {
    var getData = getQueue(data, page, 150);
    deletingRecords(getData.data, page);
}

function deletingRecords(data,page){
    console.log("deletingRecords  ==>");
    console.log("queueNo : " + page);
    console.log("totalQueue : "+totalQueue);
    console.log(data);
    var batchGuid = generateGUID();
    var changeSetGUID = generateGUID();
    var batchContents = new Array();

    for (var i = 0; i < data.length; i++) {
        if (data[i] == undefined) {
            return;
        }
        // create the request endpoint
        var endpoint1 = _spPageContextInfo.webAbsoluteUrl
            + '/_api/web/lists/getbytitle(\'' + spListName + '\')'
            + '/items(' + data[i].ID + ')';

        // create the changeset
        batchContents.push('--changeset_' + changeSetGUID);
        batchContents.push('Content-Type: application/http');
        batchContents.push('Content-Transfer-Encoding: binary');

    batchContents.push('');
    batchContents.push(batchBody);
    batchContents.push('');

    batchContents.push('--batch_' + batchGuid + '--');
    batchBody = batchContents.join('\r\n');

    var endpoint = _spPageContextInfo.webAbsoluteUrl + '/_api/$batch';

    var batchRequestHeader = {
        'X-RequestDigest': $("#__REQUESTDIGEST").val(),
        'Content-Type': 'multipart/mixed; boundary="batch_' + batchGuid + '"'
    };

    $.ajax({

Hi , @Raju Yadav ,

I test your code on my end, everything works fine. I did not get the error "page not respond" in edge browser or chrome browser.

I think there is no problem with your code.

I only test deleting 155 items. How many items do you delete? Could it be that you have a lot of items to delete, so it takes many time to finish the request?

Besides, you could try to delete all items in a HTTP request. Here is samples of code that uses the $batch that would help you:

hank you for you time & quick response

I am trying to delete 100, 150, 500 & 1500 records (records contain some text, number and some lookup fields in SP List).
In my case, it still is giving the issue/error "Page Unresponsive", (I requested for 150 records to delete by below Estimate App) , see below image

Later, I need to deleted 500 & 1500 records at time with same code as given above snippet. I tested also with 500 and 1500 records but facing same issue as shown in above image.
One more thing "In my other one SP site (PWA site) the above code is not deleting all items & leaving the some items/records undeleted". This is abnormal situation for my app. Can you please suggest me some alternative or solution for above problems?

Hi , @Raju Yadav ,

How did you pass the item id? By using a large Arrary data to store the item id?

I notice that in your given code, some item ids is not contained(id 38 and 145). Could it be the reason that some items/records undeleted?

Deletion using $batch on SharePoint (after sometime) , the browser is throwing Error, "Page become unresponsive"
