Question

当<div class>和item2位于同一world时，item1会返回undefined，但function Delivered(xCode, tNo) { document.getElementById("item1").innerHTML = "hello"; document.getElementById("item2").innerHTML = "world"; }会返回<span id="item2"></span>。

item1

但是，如果我只删除hello，<div id="details"> <div class="right" id="rightDIV">content...<span id="item1"></span>..inserted here</p> <p> more content...<span id="item2"></span> </div> </div>再次报告item2。

<div class>

我尝试将<div id="details"> <div class="left" id="leftDIV">item: <b><span id="item3"></span></b> <p>via <b>airmail;</b></p> </div> <div class="right" id="rightDIV">Status: <b>active</b> <p>item with reference <span id="item1"></span> content here <span id="item2"></span></p> <p>Thank you™</p> </div> </div>放入新#details { height:200px; width:600px; font-family: Tahoma; color: #000; margin: 0px; font-size: 12px; } #details .left{ width:33%; height:200px; padding: 15px; background-color: #fff; float: left; overflow:hidden; visibility: hidden; } #details .right{ width:40%; height:200px; padding: 15px; background-color: #ccc; float: left; overflow:hidden; visibility: hidden; } function Delivered(xCode, tCode) { document.getElementById("leftDIV").style.visibility = "visible"; document.getElementById("rightDIV").style.visibility = "visible"; document.getElementById("item3").innerHTML = tCode; document.getElementById("item1").innerHTML = tCode; document.getElementById("item2").innerHTML = xCode; }但仍未成功。我做错了什么？

编辑：我可以发布原始代码吗？对不起，先发帖。

这是我的剧本：

$.getScript( "externalfile.js" )
    .done(function( script, textStatus ) {
        d.init();
    })
});

我不确定要粘贴多少代码，因为我不确定它们是否相关：）

Answer 1

您在编写js代码后忘记调用该函数。

function Delivered(xCode, tNo) {
    document.getElementById("item1").innerHTML = "hello";
    document.getElementById("item2").innerHTML = "world";
} 

Delivered();

在html中你已经关闭了p元素，但你从未打开过一个

 <div id="details"> 
   <div class="right" id="rightDIV">
    content...<span id="item1"> </span>..inserted here</p> -----> Here
    you opened but never closed <--------- <p>more content...<span id="item2"></span>
    </div>
</div>

在Js

中这样做

function delivered(xCode, tNo) {
    document.getElementById("item1").innerHTML = "hello";
    document.getElementById("item2").innerHTML = "world";
}

delivered();

和html一样

<div id="details"> 
   <div class="right" id="rightDIV"><p>content...<span id="item1"></span>..inserted here</p>
       <p> more content...<span id="item2"></span></p>
   </div>
</div>

getElementById innerHTML未定义
