The init-crash-script Element


<init-crash-script>javascript function assigned to window.zkShowCrashMessage</init-crash-script>
[Default: see crashmsg.js]

Since 7.0.4

If the client engine stops working before even the error handling is initialized (e.g. when ZK's core scripts fail to download - zk.wpd), you will see the message below:

This element allows you to show a custom crash message when initiation by writing a javascript function which is assigned to window.zkShowCrashMessage.

For example,

	    window.zkShowCrashMessage = function (code) {
	    	var h2 = '<h2 style="background: rgb(1,133,174); text-align: center; ' 
	    			+ 'color: white; width: 700px; margin: 0 auto;">';
		    var msg = 'Ooooops!! ErrorCode: ' + code;
		    h2 = h2 + msg + '</h2>'; = 'rgb(1,133,174)';
		    document.body.innerHTML = h2;
  • Line 3, 6: The error code will be passed as a parameter, and you can take it for further use.
