Question

怎样用js获取当前url的参数值？

127.0.0.1/?xx=1
当参数xx等于1的时候输出123

Answer 1

写个函数，以方便调用：

function getUrlParameters(name)
{
var string = location.search.substr(1);
var array = string.split('&');
for(var i=0; i<array.length; i++)
{
var v = array[i].split('=');
if(v[0]==name)
{
return v[1];
}
}
return '';
}

 

调用url的参数值：

var xx_value = getUrlParameters('xx');
if(xx_value=='1')
{
alert('123');
}

Answer 2

var str=window.location;
if(str[str.length-1]=='1')
{
alert(123);

}

Answer 3

var request = [];
(function(){
var s = location.search.substr(1);
if (s) {
var ss = s.split('&');
for(var i=0; i<ss.length; i++) {
var p = ss[i].split('=');
request[p[0]] = p[1];
}
}
})();
if (request['xx'] == '1') alert('123');

Answer 4

<script>

var url=window.location.href;
var pars=url.split("?")[1].split("=");

for(var i=0;i<pars.length;i+=2){
if(pars[i]=="xx"&&pars[i+1]=="1"){
alert(123);
}
}
</script>
