JavaScript的HTML渲染与＆QUOT; .append＆QUOT; - 简单code解释

问题描述

任何人能解释这是什么code的每一行意味着什么？我试图移动＆LT;脚本＆GT; 调用语句被我的脚本生成在我的HTML的特定位置，但code总是移动这底部一个特定的表，我认为这是与此code。我想preFER通过重写此功能，它自己定位在该点插入code，其中的＆LT;脚本方式＆gt; 出现在HTML

Can Anyone explain what each line of this code means? I'm trying to move the <script> call statement to a specific position in my HTML but the code generated by my script always moves this to the bottom of one particular table and I think it has something to do with this code. I would prefer to position it myself by rewriting this function to insert the code at the point where the <script> appears in the HTML.

function initialize(instance) {
        _this = instance;
        // build html
        var realCaller = caller != null? caller:$("body");
        var cornerClass = options.showRoundCorner? "ui-corner-all ":"";
        realCaller.append("<div id='"+windowId+"' class='window_panel "+cornerClass+options.containerClass+"'></div>");
        container = realCaller.children("div#"+windowId);

在此先感谢！

推荐答案

您＆LT;脚本＆GT; 标记应留给无论它原是。四处移动它不会帮助。

Your <script> tag should be left wherever it was originally. Moving it around will not help.

我假设是使用jQuery的页面，但我不能从您发布什么确切地回答。

I am assuming the page is using jQuery, but I can't tell for sure from what you've posted.

首先，你需要把 id其中你想要的HTML插入（即＆LT的页面元素属性; DIV ID = your_id_here＆GT;＆LT; / DIV＆GT; 然后，改变这一行：

First, you need to put an id attribute on the page element where you want the HTML to be inserted (i.e. <div id="your_id_here"></div>. Then, change this line:

var realCaller = caller != null? caller:$("body");

要这样：

var realCaller = $('#your_id_here');

更换your_id_here与您的页面元素上设置的ID。

Replacing "your_id_here" with the ID that you set on the page element.

注意：由于您发布这么少的code，就很难知道是否这个修复将打破code等部位....

Note: Since you posted so little of your code, it's hard to know whether this "fix" will break other parts of the code....
