如何比较xmlhttp.responsetext? [英] how to compare xmlhttp.responsetext?

问题描述

我的代码-

document.getElementById("lblmsg").innerHTML=xmlhttp.responseText;
                if(xmlhttp.responseText == 'Available') 
                    {
                         document.getElementById("newid").value = "";
                    }       

尽管响应文本是 Available ，但在条件允许的情况下它仍然不会出现在里面?

although response text is Available but still it is not going inside if condition???

推荐答案

嗯，应该可以.

您确定响应文本完全可用吗?尝试像这样修剪响应:

Are you sure that the response text is exactly Available? Try trimming the response like this:

if(xmlhttp.responseText.trim() == 'Available')

您有权使用Firebug吗?尝试使用console.log(xmlhttp)来找出responseText的确切值.

Do you have access to firebug? Try a console.log(xmlhttp) to find out the exact value of the responseText.
