ExtJs double ActionResult share the same Js file ID conflict resolution

Project using the MVC + ExtJs achieved, access control is based on the ActionResult in Controller, there is a page due to the different parameters you need to create two new ActionResult.

Do not ask me why is based on the page level, not the data level, I just want to say that this is a problem left over from history.

Now we face the problem, that is, two ActionResult two pages share the same Js file, and this file is ExtJs, well-known, ExtJs get Dom is to get through Ext.getCmp ( ''), then, the only original Id page now becomes not unique, the event will call chaos.

Yesterday wanted a solution for several years.

Method 1: Get Page path + Id suffix, to generate a unique ID.

　　Practice, that being the case.

　　Code is as follows: var url = window.location.href;

　　Get results, obtained is ExtJs framework page path, instead of the current plane path.

Method 2: When the page is loaded, automatically generated classes of Id + Id Guid suffix, to generate a unique ID.

　　Do not practice, it is theoretically possible.

Method 3: Use Js suffix transmission parameters, such as: LogisticsMgr / MatRequireView.aspx.js MatType = 111?

　　We get the 111, then each control + Id suffix, generate a unique ID.

Ways:

Ext.namespace("JsHelper");
//获得js文件后面的参数 如test.js?user=wuf created by wufei 2013-10-25
JsHelper.GetJsParamValue = function(param) {

    var rName = new RegExp("(\\?(.*))?$")
    var jss = document.getElementsByTagName('script');
    for (var i = 0; i < jss.length; i++) {
        var j = jss[i];
        if (j.src && j.src.match(rName)) {
            var oo = j.src.match(rName)[2];
            if (oo && (t = oo.match(/([^&=]+)=([^=&]+)/g))) {
                for (var l = 0; l < t.length; l++) {
                    r = t[l];
                    var tt = r.match(/([^&=]+)=([^=&]+)/);
                    if (tt && tt[1] == param) return tt[2];
                }
            }
        }
    }
    return '';
}

Method Invocation: var idPre = JsHelper.GetJsParamValue ( "MatType"); 

So far the problem is solved, the statement ID and access ID are all plus the variable on it.

 

Note: This program is invalid because Js loaded only once, so after opening the page for parameter is incorrect.

We hope adequate guidance solutions.
