How to wait for response in $.post jQuery
ajax, javascript, jquery, post
Solution
$.post is asynchronous, you need to use $.ajax and set async to false, that way you will be able to wait for the response. You can read more about it here: http://api.jquery.com/jQuery.ajax/
Problem
PHP returns value with 1-2 second delay jQuery.post doesn't wait for response. How do you think, is it possible to fix that problem and wait for response? ``` $.post( sSource, aoData, function (data) { oCache.lastJson = jQuery.extend(true, {}, data); if ( oCache.iCacheLower != oCache.iDisplayStart ) { data.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower ); } data.aaData.splice( oCache.iDisplayLength, data.aaData.length ); abc(oCache); fnCallback(data); },"json" ); ``` Note the same function with get works well ``` $.getJSON( sSource, aoData, function (json) { /* Callback processing */ oCache.lastJson = jQuery.extend(true, {}, json); if ( oCache.iCacheLower != oCache.iDisplayStart ) { json.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower ); } json.aaData.splice( oCache.iDisplayLength, json.aaData.length ); fnCallback(json) } ); ```
