如何使用XMLHttpRequest发送多个变量？

Question

我尝试将带有Ajax请求的两个变量发送到ajax.php：

var xhReq               = new XMLHttpRequest();

xhReq.open              ( "GET", "ajax.php", false );
xhReq.setRequestHeader  ("Content-type", "application/x-www-form-urlencoded");
xhReq.send              ("cmd=ping&url=www.google.com");

我怎样才能做到这一点？

Answer 1

你正在混合一些值。

GET请求：

xhReq.open( "GET", "ajax.php?cmd=ping&url=www.google.com", true );
xhReq.send();

POST请求：

xhReq.open( "POST", "ajax.php", true );
xhReq.setRequestHeader( "Content-type", "application/x-www-form-urlencoded" );
xhReq.send( "cmd=ping&url=www.google.com" );
