JavaScript无法在AJAX加载的DIV中运行

Question

我在使javascript代码在AJAX加载的div内运行时遇到问题，我试图包含jquery选项卡，但它不起作用，ajax仅输出文本，无法识别javascript。你能帮忙的话，我会很高兴。

这是我的js代码：

var OpenedPage;

function load(url, target) {
    document.getElementById(target).innerHTML = 'Loading ...';
    if (window.XMLHttpRequest) {
        req = new XMLHttpRequest();
    } else if (window.ActiveXObject) {
        req = new ActiveXObject("Microsoft.XMLHTTP");
    }
    if (req != undefined) {
        req.onreadystatechange = function () {
            loadDone(url, target);
        };
        req.open("GET", url, true);
        req.send("");
    }
}

function loadDone(url, target) {
    if (req.readyState == 4) { // only if req is "loaded"
        if (req.status == 200) { // only if "OK"
            document.getElementById(target).innerHTML = "loaded" + req.responseText;
        } else {
            document.getElementById(target).innerHTML = "Error:\n" + req.status + "\n" + req.statusText;
        }
    }
}

function unload() {
    if (OpenedPage == "divsignin") {
        unloaddivsignin();
    }
    if (OpenedPage == "divHowto") {
        unloaddivHowto();
    }

}

function ShowHidedivsignin() {
    unload();
    OpenedPage = "divsignin";
    load("../slogin.php", "divsignin");
    $("#divsignin").animate({"height": "toggle"}, {duration: 800});
}

function unloaddivsignin() {
    OpenedPage = "";
    $("#divsignin").animate({"height": "toggle"}, {duration: 800});
}

function ShowHidedivHowto() {
    unload();
    OpenedPage = "divHowto";
    load("../howto.php", "divHowto");
    $("#divHowto").animate({"height": "toggle"}, {duration: 800});
}

function unloaddivHowto() {
    OpenedPage = "";
    $("#divHowto").animate({"height": "toggle"}, {duration: 800});
}

和HTML：

<div id="divsignin" style="display:none;width:auto"> </div>


<a onClick="ShowHidedivHowto(); return false;" href="#">help</a>

我还没有检查所有代码，但是您使用什么来触发将Javacript加载到div中？窗口/文档就绪功能仅在页面最初加载时触发一次。

尝试将以下内容用于加载到div中的内容…

<div id="tabs">
    <ul>
        <li><a href="#fragment-1"><span>One</span></a></li>
        <li><a href="#fragment-2"><span>Two</span></a></li>
        <li><a href="#fragment-3"><span>Three</span></a></li>
    </ul>
    <div id="fragment-1">
        <p>First tab is active by default:</p>
        <pre><code>$('#example').tabs();</code></pre>
    </div>
    <div id="fragment-2">
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
    </div>
    <div id="fragment-3">
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
    </div>
</div>
<script type="text/javascript">
    $("#tabs").tabs();
</script>

请注意，脚本标记位于结尾处，因此将在加载选项卡后对其进行解析。

另一种方法是修改AJAX成功时调用的函数并添加

 $("#tabs").tabs();

至最后-再次确保代码仅在内容加载后才运行。
