本文介绍了一个用于从当前页面URL中获取指定参数值的JavaScript函数。该函数通过正则表达式匹配URL中的参数名并返回对应的值。
function getParameterValue(name) {
var url = window.top.location.href;
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec(url);
if( results == null )
return "";
else
return results[1];
}
var url = window.top.location.href;
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec(url);
if( results == null )
return "";
else
return results[1];
}
