在变量追加 [英] Variables in append

问题描述

我要插入可变数量为追加，使具有可变IMG文件列表。我有这个code：

I want to insert variable number into an append to make lists with variable img file. I have this code:

<form method="POST">
     <div id="dynamicInput">
          Entry 1<br><input type="text" name="myInputs[]">
     </div>
     <input type="button" value="Add another text input" onClick="addInput('dynamicInput');">
</form>

var counter = 1;
var limit = 3;
function addInput(divName){
     if (counter == limit)  {
          alert("You have reached the limit of adding " + counter + " inputs");
     }
     else {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = "Entry " + (counter + 1) + " <br><input type='text' name='myInputs[]'>";
          document.getElementById(divName).appendChild(newdiv);
          counter++;
     }
}

这使得变量的形式输入，计数器变量，但我想使这个以

This make variable form inputs with the counter variable, but i want to make this with a

<li>, check this:

 <ul class="popupimg">
                        <li><a href="Imagenes/img1.png" class="image-link"><img src="Imagenes/img1.png" alt="Img1" title="Img1"></a></li>
                        <li><a href="Imagenes/img2.png" class="image-link"><img src="Imagenes/img2.png" alt="Img2" title="Img2"></a></li>
                        <li><a href="Imagenes/img3.png" class="image-link"><img src="Imagenes/img3.png" alt="Img3" title="Img3"></a></li>
                        <li><a href="Imagenes/img4.jpg" class="image-link"><img src="Imagenes/img4.jpg" alt="Img4" title="Img4"></a></li>
                        <li><a href="Imagenes/img5.jpg" class="image-link"><img src="Imagenes/img5.jpg" alt="Img5" title="Img5"></a></li>
                        <li><a href="Imagenes/img6.jpg" class="image-link"><img src="Imagenes/img6.jpg" alt="Img6" title="Img6"></a></li>

                    </ul>

添加里，并与可变数目在img，代替3或4，为每个点击计数器数字

Adding the li and the img with variable number, instead 3 or 4, a counter number for each click.

我怎样才能做到这一点？谢谢你。

How can i do that? Thanks.

推荐答案

如果你不介意的jQuery（我的preference），下面的演示使用虚拟剧本元素（未知类型）举行的新项目（比code在行字符串好得多）的模板：

If you don't mind jQuery (my preference), the following demonstrates using a dummy script element (with unknown type) to hold a template for new items (much nicer than in-line strings in the code):

<script id="template" type="text/template">
    <li><a href="Imagenes/img{n}.png" class="image-link"><img src="Imagenes/img{n}.png" alt="Img{n}" title="Img{n}"/></a></li>
</script>

的jsfiddle： http://jsfiddle.net/TrueBlueAussie/vs6K9/1/

    var $images = $('#Images');
    var template = $('#template').html();
    template = template.replace(/\{n\}/g, counter);
    $images.append(template);

在code刚刚取代了{N}标记你的新值，那么追加的模板。它采用了常规的前pression与先按g 全局标志为替换通常仅替换第一个匹配。

The code just replaces the {n} marker with your new value then appends the template. It uses a regular expression with the g global flag as replace normally replaces only the first match.

我只是附加的图像，以一个新的div和留在原处现有code。

I just appended the images to a new div and left your existing code in place.

根据的评论，如果你想要的图像编号开始在说6，使用：

Based on the comment, if you want the image numbers to start at say 6, use this:

    var $images = $('#Images');
    var template = $('#template').html();
    template = template.replace(/\{n\}/g, $images.children().length +6);
    $images.append(template);

的注：现在也取得了图像列出UL，而不是DIV（我的坏）的：）
