附加变量(Variables in append)

我想在变量中插入变量号以使变量img文件生成列表。我有这个代码：

<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++; } }

这使变量形式输入与计数器变量，但我想用一个

<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>

添加带有可变数字的li和img，而不是3或4，每次点击都有一个计数器编号。

我怎样才能做到这一点？谢谢。

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++; } }

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>

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

How can i do that? Thanks.

如果你不介意jQuery（我的偏好），下面演示使用一个虚拟script元素（具有未知类型）来保存新项目的模板（比代码中的内联字符串好得多）：

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

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

代码只是用新值替换{n}标记，然后附加模板。它使用带有g全局标志的正则表达式作为replace通常仅替换第一个匹配。

我只是将图像附加到一个新div并将现有代码保留在原位。

根据评论，如果您希望图像编号从6开始，请使用：

JSFiddle： http ： //jsfiddle.net/TrueBlueAussie/vs6K9/26/

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

注意：现在也使图像列表为UL而不是DIV（我的坏） :)

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):

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

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

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.

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

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

JSFiddle: http://jsfiddle.net/TrueBlueAussie/vs6K9/26/

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

Note: also now made the images list a UL instead of DIV (my bad) :)
