使用计数器和amp;添加Div的点击次数限制 [英] Add Div's on Click with counter & limit

问题描述

我想用下面的代码添加一些功能，只有5次才能单击添加按钮.

I would like to add some functionality with the below code that only 5 times one can click the add button.

我也想为每个复制添加一个删除按钮，因此当单击时，删除div并减少5次计数.

Also I would like to add a delete button with every replicated so when clicked, div is deleted and the counter of the 5 times is decreased.

HTML:

    <button id="button" onlick="duplicate()">Add another plan</button>
<div id="duplicater">
    <p>Choose Your Mobile Plan</p>
    <select>
        <option value="1">Package 1</option>
        <option value="2">Package 2</option>
        <option value="3">Package 3</option>
        <option value="4">Package 4</option>
        <option value="5">Package 5</option>
        <option value="6">Package 6</option>
    </select>
</div>

JS:

document.getElementById('button').onclick = duplicate;

var i = 0; var original = document.getElementById('duplicater');

function duplicate() {
    var clone = original.cloneNode(true); // "deep" clone
    clone.id = "duplicater" + ++i; // there can only be one element with an ID
    original.parentNode.appendChild(clone); }

推荐答案

您可以添加一个按钮来删除元素，如下所示:

You can add a button to delete the element like this:

<button id="button">Add another plan</button>
<div id="duplicater">
<p>Choose Your Mobile Plan</p>
<select>
    <option value="1">Package 1</option>
    <option value="2">Package 2</option>
    <option value="3">Package 3</option>
    <option value="4">Package 4</option>
    <option value="5">Package 5</option>
    <option value="6">Package 6</option>
</select>
    <button class='removebutton'>Delete</button>
</div>

您可以启用使用jquery单击该函数的功能:

You can enable a function to fire when it's clicked using jquery:

$('body').on('click', ".removebutton", remove);

最后，删除处理程序可以删除所单击的元素:

Finally, the remove handler can remove the clicked element:

function remove() {
if (count > 1) {
    if ($(this).parent().attr('id') != 'duplicater') {
        $(this).parent().remove();
        count--;
    } else {
        alert("You can't delete the first plan");
    }
} else {
    alert("You can't delete the first plan");
}
}

我对ReeCube使用了类似的计数器.

I've used a similar approach to the counter as used by ReeCube.

由于它使用jquery，因此您需要从本地计算机或其他位置将其包括进来.

As this uses jquery, you need to include it, either from your local machine or from somewhere else e.g.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">

所有js代码都应包装在标准的jQuery ready函数中:

All the js code should be wrapped in the standard jquery ready function:

$(function(){
    // Put your js code here.
});
