    <p>I am using jquery in our application. We have some javascript code which validates if you modified any data. If user enter some values and click on some other link or something else then pop up comes which say "Are you sure you want to navigate away from this page? ... Press OK to continue, or Cancel to stay on the current page." Its working fine in IE7, IE9 and and firefox and other browser. But in IE8 it generates alert box which says "Stop running this script. The script on this page is causing your wb browser to run slowly If it continue to run , your computer might become unresponsive".</p> <p>Following is my javascript which cause problem.</p> <pre><code>$(document).ready(function() { // Flag to display warning. // If needToConfirm = true warning message will be displayed. needToConfirm = false; window.onbeforeunload = askConfirm; function askConfirm() { if (needToConfirm) { // Message to be displayed in Warning. return "Your data will be lost."; } } // Add all form elements in argument. $("select,input,textarea").live('change',function () { needToConfirm = true; }); // Add all form elements in argument. $("select,input,textarea").live('keypress',function () { needToConfirm = true; }); // Use "class = noWarning" for save or cancel button. $(".noWarning").click(function () { needToConfirm = false; }); }); </code></pre> <p>Is it problem of "window.onbeforeunload = askConfirm;" code some thing else.</p> <blockquote> <p>EDIT</p> </blockquote> <p>Found that following line cause problem in IE8</p> <pre><code>$("select,input,textarea").live('keypress',function () { needToConfirm = true; }); </code></pre> <p>Is it any other alternative for this.</p>

    1. CONot really sure but you could start with this. From the jQuery docs: `As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live().` If you are still getting the error then you can rule this out.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
