Question

I have a mystic problem with sending parametrs from one page to another.

In one of ExtJs methods i send parameter by POST to another page:

autoLoad : {  
url : url_servlet+'form.jsp',  
params: str,
scripts: true  
}

But i dont know how to get this parametr in JavaScript. Okey i says, and sent parameter in url:

 url : url_servlet+'form.jsp?ss=333'

And in another page:

            function param(Name){
            var Params = location.search.substring(1).split("&");
            var variable = "";
            for (var i = 0; i < Params.length; i++){
                if(Params[i].split("=")[0] == Name){
                    if (Params[i].split("=").length > 1)
                        variable = Params[i].split("=")[1];
                return variable;
                }
            }
            return "";
        } 

        var s =param('ss');
        alert(s);

And see empty alert.

in firebug i try:

window.location.search

and get " ".

Whats wrong? I read several examples and everywere see code like this.

What’s likely going on here is that ExtJS loads an entire page from a remote location into the current page.

When this happens, the code that gets run as a result of the load, will execute in the current page (which probably doesn’t have the ss=xyz parameter at all).

However, your form.jsp should have access to the query string and can inject that into the page it returns to ExtJS.

Another option is to somehow pass that data from JavaScript once the page is loaded, but I don’t know enough about ExtJS to tell you how that could be done.
