ie9不显示由js填充的表

IE 9 not showing table populated by js

本文关键字：填充 js 显示 ie9      更新时间：2023-09-26

我有一个问题，' adddeditems '表不显示在IE 9中，但如果在Firefox 30上使用，它应该显示。在IE中，它发送post数据，当我用开发人员工具检查HTML时，它会显示页面上的HTML元素。我试着看看是否设置表显示块，但没有变化。

这段代码的目的是允许用户从下拉列表中选择他们想要添加的设备类型，然后能够从Foo或Bar列表中添加任意数量的项目到表中，以便在items[] post变量中发送。该表的每一行都有一个删除按钮，以便用户可以删除错误添加的设备。

下面是HTML文件:

<html>  
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    </head>
    <body>
    <form method="post">
        <ul>
            <li id="EquipmentSelector" >
                <label for="EquipmentType">Equipment Type</label>
            <div>
                <select id="EquipmentType" name="EquipmentType">
                    <option value="" selected="selected"></option>
                    <option value="0" >Foo</option>
                    <option value="1" >Bar</option>
                </select>
            </div>
        </li>
        <li id = "FooHolder">
            <label class="description" for="Foo">Foo</label>

                <select id="Foo">
                    <option value="" selected="selected"></option>
                        <option value="0" >Foo Zero</option>
                        <option value="1" >Foo One</option>
                        <option value="2" >Foo Two</option>
                        <option value="3" >Foo Three</option>
                </select>


            <input type = "button" value = "Add Foo" id = "FooClick" ></input>
        </li>
        <li id = "BarHolder">
            <label class="description" for="Bar">Bar</label>
                <select id="Bar">
                    <option value="" selected="selected"></option>
                    <option value="0" >Bar Zero</option>
                    <option value="1" >Bar One</option>
                    <option value="2" >Bar Two</option>
                    <option value="3" >Bar Three</option>
                </select>

            <input type = "button" value = "Add Bar" id = "BarClick" ></input>
        </li>
        <li>
        <table>
                    <tbody  id = "addedItems">
                    </tbody>    
        </table>
        </li>
        <li>
            <input type= "submit" id="saveForm" name="submit" value="Submit"  />
        </li>
    </ul>
    </form>
    <script src = "IEerror.js"></script>
    </body>
</html>

下面是IEerror.js文件:

function prepareEventHandlers(){
    document.getElementById("EquipmentType").onchange = function(){
        var equipType = document.getElementById("EquipmentType").value
        if(equipType === "1"){
            document.getElementById("BarHolder").style.display = "block";
            document.getElementById("FooHolder").style.display = "none";
        } else if(equipType === "0"){
            document.getElementById("FooHolder").style.display = "block";
            document.getElementById("BarHolder").style.display = "none";
        } 
    }
    document.getElementById("FooHolder").style.display = "none";
    document.getElementById("BarHolder").style.display = "none";

    function removeDiv() {
        var parentId = $(this).parent().parent().attr("id");
        $('#' + parentId).remove();
    }

    var myNum = 0;
    function addItem(getFromId){
        var addTag = document.getElementById("addedItems");
        var addVariable = document.getElementById(getFromId).value;
        var possibleId = getFromId + addVariable;
        if(!document.getElementById(possibleId)){
            var newTr = document.createElement("tr");
            newTr.id = possibleId;
            var myText = $('#'+ getFromId).find(":selected").text();
            var newTd = document.createElement("td");
            newTd.appendChild(document.createTextNode(myText));
            newTr.appendChild(newTd);
            addTag.appendChild(newTr);
            var submissionInput = document.createElement("input");
            submissionInput.name = "item[]";
            submissionInput.type = "hidden";
            submissionInput.value = myText;
            newTd.appendChild(submissionInput);
            var deleteInput = document.createElement("input");
            deleteInput.type = "button";
            deleteInput.value = "Delete";
            deleteInput.id = myNum;
            myNum += myNum;
            deleteInput.onclick = removeDiv;
            var deleteTd = document.createElement("td");
            deleteTd.align = "right";
            document.getElementById(possibleId).appendChild(deleteTd);
            deleteTd.appendChild(deleteInput);
        }
    }
    document.getElementById("BarClick").onclick = function(){
        addItem("Bar");
    };
    document.getElementById("FooClick").onclick = function(){
        addItem("Foo");
    };
};



window.onload = function(){
    prepareEventHandlers();
};
编辑:

这里是jsfiddle的链接:http://jsfiddle.net/DTCav/xJVJR/1/

多么可怕的代码，但让我们开始吧:

  1. 验证HTML。即你的<html>包含HTML5 <header>而不是<head>

  2. 为什么使用原生JS和jQuery通过彼此?为什么不坚持使用jQuery呢?

  3. 无论如何，我挑剔的<aside>，解决你的问题改变你的<table>代码为:

    <table>
    <tbody id="addedItems">
    </tbody>
</table>

这是因为IE9将在空的<table>中创建一个空的<tbody>，并将其用作表占位符，您将<tr>和<td>标签直接注入<table>
