Question

你好我们在运行时开发一个表单并在div中附加元素。

但是当将div的内容复制到另一个页面时，它没有显示任何内容，好像没有附加任何内容。你能告诉我这是什么问题......

<form>

    <div class="dynamicInput" id="dynamicInput">
        /*all dynamic elements are appended here as per javascript coding . but not showing in another page only static things are showing shuch as
        <input type="text" name="a" /> */
    </div>
    <input type="submit" value="submit_form" onclick="f();" />
</form>

<script>
    var counterText = 0;
    var counterRadioButton = 0;
    var counterCheckBox = 0;
    var counterTextArea = 0;
    var lb = "";
    var name = "";

    function addAllInputs(divName, itemName) {

        var newdiv = document.createElement('div');
        switch (itemName) {
            case 'text':
                lb = prompt("enter label name");
                name = prompt("enter name for div attribute");
                //newdiv.innerHTML = " "+(counterText + 1)+ " "+ lb + " <br><input type='text' name='myInputs[]'>";
                newdiv.innerHTML = " " + lb + " <br><input type='text'>";
                newdiv.setAttribute("id", name);
                newdiv.setAttribute("name", name);
                counterText++;
                document.getElementById(divName).appendChild(newdiv);
                break;
            case 'radio':
                {
                    var n = prompt("How many number of elements do you need");
                    lb = prompt("enter label name");

                    newdiv.innerHTML = " " + lb + "<br>";
                    document.getElementById(divName).appendChild(newdiv);
                    for (var i = 0; i < n; i++) {
                        var newdiv1 = document.createElement('div');
                        lb = prompt("enter label name");
                        name = prompt("enter name for div attribute");
                        newdiv1.innerHTML = " " + lb + "<input type='radio'>";
                        newdiv1.setAttribute("id", name);
                        newdiv1.setAttribute("name", name);
                        counterRadioButton++;
                        document.getElementById(divName).appendChild(newdiv1);
                    }
                    counterRadioButton++;
                    break;

                    newdiv.setAttribute("id", name);
                    newdiv.setAttribute("name", name);
                    document.getElementById(divName).appendChild(newdiv);
                    counterCheckBox++;
                } else if (n > 1) {
                    var newdiv1 = document.createElement('div');
                    lb = prompt("enter label name");
                    newdiv1.innerHTML = " " + lb;

                        counterCheckBox++;
                    }
                }

                break;

            case 'textarea':
                lb = prompt("enter label name");

我认为你应该等待DOM准备好了：

<script>
    $( document ).ready( function() {
        document.getElementById("copy").innerHTML=sessionStorage.getItem("page1content");
    } )
</script>

以这种方式使用你的代码对我来说非常有用。

使用javascript将1 div内容复制到另一个页面div
