Javascript / jquery .load传递变量

Question

Stuck on a jquery/javascript function that is attempting to .load a set PHP script but passing get variable parameters. 卡在试图加载一个PHP脚本但传递get变量参数的jquery / javascript函数上。 As an aside this is set to happen automatically after 5 seconds. 顺便说一句，这将设置为5秒钟后自动发生。 New to posting here but have read a lot of posts and can't seem to find exactly what I am doing wrong. 此处新发布的帖子，但已经阅读了很多帖子，而且似乎找不到确切的我在做错的事情。

This function works: 此功能有效：

function LoadMyPhpScript()
{
    $('#MyDiv').load('hello.php');
}
setTimeout(LoadMyPhpScript,5000);

This function does not work: 此功能不起作用：

function LoadMyPhpScript2(cPhpParamString)
{
    var strURL = 'hello.php';
    strURL = strURL + cPhpParamString;
    $('#MyDiv2').load(strURL);
}
setTimeout(LoadMyPhpScript2('?MyVar1=0&MyVar2=1'),5000);

Here's the hello.php 这是hello.php

<?php
echo '<p>Hello, I am loaded with get values of MyVar1=' . $_GET['MyVar1'] . ', MyVar2=' . $_GET['MyVar2'] . '</p>';
?>

Note: this is just a mock-up, would use regex to validate gets, etc in production. 注意：这只是一个模型，将在生产中使用正则表达式来验证获取等。

RESOLVED 解决

Here is what I ended up with, thank you! 这就是我最后得到的，谢谢！

function LoadMyPhpScript1(cPhpParamString)
{
    $('#MyDiv1').load('hello.php'+cPhpParamString);
}
setTimeout(function() { LoadMyPhpScript1('?MyVar1=0&MyVar2=1'); },5000);

Answer 1

When you do this: 执行此操作时：

LoadMyPhpScript2('?MyVar1=0&MyVar2=1')

You are executing the function and passing the result to setTimeout 您正在执行该函数并将结果传递给setTimeout

Try this: 尝试这个：

setTimeout(function() { LoadMyPhpScript2('?MyVar1=0&MyVar2=1'); },5000);

However, sending the url querystring like that is an odd way of doing it. 但是，像这样发送url查询字符串是一种奇怪的方式。 Something like this might be better: 这样的事情可能会更好：

function LoadMyPhpScript2(myVar1, myVar2)
{
    var strURL = 'hello.php';
    $('#MyDiv2').load(strURL, { myVar1: myVar1, myVar2: myVar2 });
}
setTimeout(function() { LoadMyPhpScript2(0, 1); },5000);

Better try this way: 最好这样尝试：

File help3.html: 文件help3.html：

<html>
    <head>
    <script type='text/javascript' src='http://code.jquery.com/jquery-1.8.3.js'></script>
    <script type='text/javascript'>
    function LoadMyPhpScript2(cPhpParamString)
    {
        var strURL = 'help3.php';
        strURL = strURL + cPhpParamString;

      $.ajax({
      url: strURL
      }).done(function(data) { // data what is sent back by the php page
       $('#MyDiv').html(data); // display data
      });


    }
    setTimeout(LoadMyPhpScript2('?MyVar1=0&MyVar2=1'),5000); 

    </script>
    </head>

    <body>

      <div id="MyDiv">

      </div>

    </body>
    </html>

File help3.php: 文件help3.php：

<?php
echo '<p>Hello, I am loaded with get values of MyVar1=' . $_GET['MyVar1'] . ', MyVar2=' . $_GET['MyVar2'] . '</p>';
?>

Test on my localhost, and both files on the same folder. 在我的本地主机上测试，并将这两个文件放在同一文件夹中。
