jQuery Grid Plugin - jqGrid

Dear All:

I am useing jqgrid-4.4.1 and I found Firefox/Chrome didn't completely load Modules.

There are some errors in the console.When I clicked custimized Add button,it didn't work.

In IE and Safari it's OK.Here is the error detail.

I fonud this artical. 

/blog/?page_id=393/bugs/jqgrid-3-7-2-bug-with-ie8-while-using-jqgrid-debugging/#p21510

And I changed the section in jquery.jqGrid.js as below.It works good.

So I want to confirm that is this a bug.

Before Change:

var filename;

for(var i=0;i<modules.length; i++)

{

if(modules[i].include === true) {

filename = pathtojsfiles+modules[i].incfile;

if(jQuery.browser.safari) {

jQuery.ajax({url:filename,dataType:'script', async:false, cache: true});

} else {

if (jQuery.browser.msie) {

document.write('<script charset="utf-8" type="text/javascript" src="'+filename+'"></script>');

} else {

IncludeJavaScript(filename);

}

}

}

}

After Change:

var filename;

for(var i=0;i<modules.length; i++)

{

if(modules[i].include === true) {

filename = pathtojsfiles+modules[i].incfile;

if(jQuery.browser.safari) {

jQuery.ajax({url:filename,dataType:'script', async:false, cache: true});

} else {

if (jQuery.browser.msie) {

document.write('<script charset="utf-8" type="text/javascript" src="'+filename+'"></script>');

} else {

//IncludeJavaScript(filename);

document.writeln("<script type='text/javascript' src='"+filename+"'></script>");

}

}

}

}

Best Regard,
