IE 8 getSelection().anchorOffset alternative

Question

I have got a Javascript code, which works well for modern browsers:

var offset = getSelection().anchorOffset;
var node   = getSelection().anchorNode;
         


        

Answer 1

There is a solution. It is possible to extend browser's object model using Rangy library:

window.getSelection = rangy.getSelection

As it may take some time for Rangy to init and as we will not need this for modern browsers, some more workaround:

/* 
IE 8 getSelection() missing object and properties simple hack
*/
if (window.getSelection == undefined) {                /* IE? */
    var wgS = setInterval(function(){                  /* wait for Rangy */
        if (rangy.initialized) {
            window.getSelection = rangy.getSelection;  /* do the stuff */
            clearTimeout(wgS);                         /* exit */
        }
     }, 10);
}
