Javascript将名称数组（）增加1

javascript arrays

Javascript将名称数组（）增加1,javascript,arrays,Javascript,Arrays,我有以下javascript代码，在用户需要添加更多行时复制容器： <script type="text/javascript"> //<![CDATA[ document.getElementById('button').onclick = duplicate; var i = 0; var original = document.getElementById('inlinedup'); function duplicate() {

我有以下javascript代码，在用户需要添加更多行时复制容器：

<script type="text/javascript">
    //<![CDATA[ 
    document.getElementById('button').onclick = duplicate;
    var i = 0;
    var original = document.getElementById('inlinedup');

    function duplicate() {
        var clone = original.cloneNode(true); // "deep" clone
        clone.id = "inlinedup" + ++i; // there can only be one element with an ID
        original.parentNode.insertBefore(clone, original.nextSibling);
    }
    //]]>  
</script>

请参阅小提琴，以了解工作示例

<script type="text/javascript">
    //<![CDATA[ 
    document.getElementById('button').onclick = duplicate;
    var i = 0;
    var original = document.getElementById('inlinedup');

    function duplicate() {
        var clone = original.cloneNode(true); // "deep" clone
        clone.id = "inlinedup" + ++i; // there can only be one element with an ID
        original.parentNode.insertBefore(clone, original.nextSibling);
    }
    //]]>  
</script>

呃。。。你不需要

<script type="text/javascript">
    //<![CDATA[ 
    document.getElementById('button').onclick = duplicate;
    var i = 0;
    var original = document.getElementById('inlinedup');

    function duplicate() {
        var clone = original.cloneNode(true); // "deep" clone
        clone.id = "inlinedup" + ++i; // there can only be one element with an ID
        original.parentNode.insertBefore(clone, original.nextSibling);
    }
    //]]>  
</script>

如果您有：

<script type="text/javascript">
    //<![CDATA[ 
    document.getElementById('button').onclick = duplicate;
    var i = 0;
    var original = document.getElementById('inlinedup');

    function duplicate() {
        var clone = original.cloneNode(true); // "deep" clone
        clone.id = "inlinedup" + ++i; // there can only be one element with an ID
        original.parentNode.insertBefore(clone, original.nextSibling);
    }
    //]]>  
</script>

<input type="text" name="prepmethod[]" value="1" />
<input type="text" name="prepmethod[]" value="2" />
<input type="text" name="prepmethod[]" value="3" />
<input type="text" name="prepmethod[]" value="4" />

然后，服务器上生成的数组将是

数组（1,2,3,4）

。就这样。你什么都不用做

<script type="text/javascript">
    //<![CDATA[ 
    document.getElementById('button').onclick = duplicate;
    var i = 0;
    var original = document.getElementById('inlinedup');

    function duplicate() {
        var clone = original.cloneNode(true); // "deep" clone
        clone.id = "inlinedup" + ++i; // there can only be one element with an ID
        original.parentNode.insertBefore(clone, original.nextSibling);
    }
    //]]>  
</script>

作为补充说明，我建议只设置

clone.id=“”，除非您以后有特殊需要使用ID。

啊，好的，我想我需要为每个ID分配单独的密钥。我会试一试，然后告诉你。谢谢好的，我在想我需要给每一个都分配单独的密钥。我会试一试，然后告诉你。谢谢好的，我在想我需要给每一个都分配单独的密钥。我会试一试，然后告诉你。谢谢好的，我在想我需要给每一个都分配单独的密钥。我会试一试，然后告诉你。谢谢，我认为名称
