Question

我有几个在我的索引页面中加载的JS脚本，包括一个包含

的JS脚本

function ajaxrequest(php_file, purpose, var1, var2, var3, var4, var5, var6, var7, var8, where) {
    var request = getXMLHTTP(); // call the function for the XMLHttpRequest instance

    // create pairs index=value with data that must be sent to server
    var the_data = 'purpose=' + purpose + '&var1=' + var1 + '&var2=' + var2 + '&var3=' + var3 + '&var4=' + var4 + '&var5=' + var5 + '&var6=' + var6 + '&var7=' + var7 + '&var8=' + var8;

    request.open("POST", php_file, true); // set the request

    // adds  a header to tell the PHP script to recognize the data as is sent via POST
    request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    request.send(the_data); // calls the send() method with datas as parameter

    // Check request status
    // If the response is received completely, will be transferred to the HTML tag with tagID
    request.onreadystatechange = function() {
        if (request.readyState == 4) {
            document.getElementById(where).innerHTML = request.responseText;
        }
    };
}

在调用此函数之前，所有内容（包括与上述函数在同一文件中找到的其他JS函数）都能正常工作。这个函数每次都有效，但任何JS函数，PHP都需要，session_start（）似乎都在重置＆＃39;并需要重新加载。这是正常的，如果没有，请你协助纠正这个问题吗？

如果您希望该代码影响AJAX完成打印后创建的任何新元素，则需要在加载AJAX页面后调用依赖页面项的函数。

当我调用一个母函数时，我将我在JS中运行的所有函数包装起来，有点像这样：

// In the beginning
function init(){
    // Functions that need to be fired when any page loads
    // etc etc
    // Code goes here...
}    

function ajaxrequest(php_file, purpose, var1, var2, var3, var4, var5, var6, var7, var8, where) {
 // ...
    // Check request status
    // If the response is received completely, will be transferred to the HTML tag with tagID
    request.onreadystatechange = function() {
        if (request.readyState == 4) {
            document.getElementById(where).innerHTML = request.responseText;
            init();
        }
    };
}

我的AJAX函数关闭了其他JS和PHP的东西
