javascript - 使用 http.send() ajax

Question

if(document.getElementById(callerName).checked) {
    //alert(callerName);        
    var poststr = "field=" + escape(encodeURI(callerName)) +
      "&op=add" + "&nocache=" + nocache;
}
else {
    //alert(callerName);
    var poststr = "field=" + escape(encodeURI(callerName)) + 
      "&op=del" + "&nocache=" + nocache;
}
http.send(poststr);

当我收到$_POST['field']'％20'时，有空格..任何解决方案来获得准确的字符串？

Answer 1

PHP：

$field = urldecode($_POST['field']);

Answer 2

您同时使用escape和对数据进行双重转义encodeURI。另外，我建议您encodeURIComponent改用。尝试更改为：

var poststr = "field=" + encodeURIComponent(callerName) + 
  "&op=add&nocache=" + nocache;
