="" text="Save">

but it works fine in IE not in google chrome
I am stuck in this Please help me to resolve this

What I have tried:

<asp:Button ID="btnSave" runat="server" CssClass="Button" AccessKey="s" OnClientClick="return SaveData()"
                        Text="Save"/>

Javascript code:

function SaveData()
{
    var sJSON=Main_GetDataSave();
    sJSON='Save^'+sJSON;
    UserDataServerCall(sJSON,'');
    return false;
}

Any errors in the browser console?

Try using the built-in Javascript debugger[^] to step through your SaveData function to see what happens.

I have checked in Javascript debugger and it throws 1 error "Uncaught TypeError: oCtrlTable.getAttribute is not a function"

var oRow,oCtrlTable,iFieldID,oPromptCell;
oRow=oTable.rows[i];
oCtrlTable=oRow.cells[1].childNodes[0].childNodes[0];
iFieldID=oCtrlTable.getAttribute('FieldID');//error throws here

That would suggest there's a difference in the DOM tree between IE and Chrome.

That looks like a fairly fragile way of locating an element. Surely there must be a better way? For example, you could add a CSS class to identify the element, and then use querySelector[^] to find the element within the row.

Solution 1

Try the example here: Button.OnClientClick Property (System.Web.UI.WebControls) | Microsoft Docs[^] and see if that works.
It might also be needed to add a semicolon in:

return SaveData();
