Disable parent window while child window is opened using javascript??

[BobbyRachel]

1. I have a parent window named worklist.jsp
2. Parent window has a button. on click of the button, it calls a function named getEventLogUser().
3. getEventLogUser() function in turns calls a function named popupWindowWithPost() which opens the child window. both the function is in separate js file(utility.js)..
4. My need is, i have to disable the parent window when child is opened.

worklist.jsp:

 <div class="claro" id="menuDiv21" onclick="setWidgetproperty(this.id,'x','navMenu21');" onmousedown="setMenuBarProperty('navMenu21');" onmouseup="setDocStyle(this.id)" style="border:1px dotted white; left: auto; position: absolute; top: 620px;">
         <div dojotype="dijit.MenuBar" id="navMenu21" style="font-size:11pt;" title="MenuBar">
              <div dojotype="dijit.MenuBarItem" id="SearchMenu21" onclick="getEventLogUser();setMenuId(this.id);" style="font-size:11pt;" title="menuBarItem">
                   <img class="images" id="SearchMenu21" name="search5.png" onclick="setImgProperty(this.id)" src="images/uploads/search.png" style="height:20px; width:20px;">
                   Search
              </div>
    </div>
    </div>

utility.js:

function getEventLogUser(){
    		var dummyvar = document.getElementById("CWPROCESSEVENTLOG.OBJECT_ID").value;
    		popupWindowWithPost("eventLogUser.jsp",'height=600px,width=960px,top=50px,left=150px,scrollbars=no,sizable=yes,toolbar=no,statusbar=no','processManager',dummyvar);
    }
    function popupWindowWithPost(url, windowoption, name, params)
    {
             var form = document.createElement("form");
             form.setAttribute("method", "post");
             form.setAttribute("action", url);
             form.setAttribute("target", name);
             var input = document.createElement('input');
             input.type = 'hidden';
             input.name = "PARAM";
             input.value = params;
             form.appendChild(input);
    		 document.body.appendChild(form);
             window.open(url, name, windowoption);
    		 form.submit();
             document.body.removeChild(form);
    }

Each window is completely independent - the only way to do what you want is to put both in the same window.

JavaScript has changed significantly since 2009 when that script was written. Most of the browsers that allowed that script to work are now long dead.

The modal setting in that script is ignored by some browsers and can be overridden in most others. Many browsers even allow you to specifically direct window.open calls to another tab in the same window so that making that modal becomes meaningless.

The only way to ensure that it is not easily bypassed or blocked is to do it all within the one window.
