wants to add delay in newform load

Question

I created custom SharePoint New form with lots of custom code. So, when I load the form by clicking on New Item, it will open sometimes correctly and sometimes it gave error:

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.

But after one or two refresh its again working fine.

Please help me with this that how can I get the newform without abaove error in one go.

It is more than likely a syncronization issue. JS loads asyncronously is SharePoint. It is good to put Page_Load code within a function and call it using one of SharePoint's body onload functions; instead of using $(document).ready(function () { }); or $(function () { }); type operations on page load. Try one of these:

ExecuteOrDelayUntilScriptLoaded(yourFunction, "SP.JS");

or

_spBodyOnLoadFunctionNames.push("yourFunction");

There are core JS files used by SharePoint which need to be loaded first before any of your custom code will render properly. Make sure you are letting these files load before your custom functions. This should help.
