将按钮移出容器时,单击时克隆 div 会中断吗?
Cloning div on click breaks when moving the button out of container?
我找到了这个漂亮的 js fiddle,它几乎完全符合我的需要
然而,它克隆按钮的父级和 id 喜欢让按钮与实际被克隆的 div 分开。 (如果您使用删除按钮将克隆按钮放回容器中,它将再次正常工作)
总而言之,我正在努力完成 3 件事。
1. 将正在复制的 div 之外的按钮(1 个按钮)
2. 将重复的数量限制为总共 6 个。(或任何可变变量)
3.更新<h4>
内容,将数字1改为下一个数字。即:(1-6)
虽然我涉猎,但我不是很精通 JS。如果有人有时间帮我弄清楚以上内容,我将不胜感激!这是我一直在玩的JS FIDDLE。
谢谢!
var regex = /^(.+?)(\d+)$/i;
var cloneIndex = $(".clonedInput").length;
function clone(){
$(this).parents(".clonedInput").clone()
.appendTo("body")
.attr("id", "clonedInput" + cloneIndex)
.find("*")
.each(function() {
var id = this.id || "";
var match = id.match(regex) || [];
if (match.length == 3) {
this.id = match[1] + (cloneIndex);
}
})
.on('click', 'button.clone', clone)
.on('click', 'button.remove', remove);
cloneIndex++;
}
function remove(){
$(this).parents(".clonedInput").remove();
}
$("button.clone").on("click", clone);
$("button.remove").on("click", remove);
您可以 select 最后出现的 .clonedInput
并克隆它,然后将其插入到原始元素之后:
var regex = /^(.+?)(\d+)$/i;
function clone(){
var cloneIndex = $(".clonedInput").length + 1;
if (cloneIndex > 6) return;
$source = $(".clonedInput").last();
$source.clone()
.insertAfter($source)
.attr("id", "clonedInput" + cloneIndex)
.find("*")
.each(function() {
var id = this.id || "";
var match = id.match(regex) || [];
if (match.length == 3) {
this.id = match[1] + (cloneIndex);
}
})
.on('click', 'button.remove', remove)
.find('label').html('Learning category ' + cloneIndex + ' <span class="requiredField">*</span>');
}
function remove(){
$(this).parents(".clonedInput").remove();
}
$("button.clone").on("click", clone);
$("button.remove").on("click", remove);

<div id="clonedInput1" class="clonedInput">

我认为以下是您要实现的目标,您必须添加另一个变量 cloned_nbr
和 clones_limit
来控制克隆的 div:
var cloneIndex = 1;
var clones_limit = 4;
var cloned_nbr = $(".clonedInput").length-1; //Exclude Default (first) div
function clone()
{
if(cloned_nbr<clones_limit)
{
cloneIndex++;
cloned_nbr++;
var new_clone = $(".clonedInput").first().clone();
new_clone.attr("id", "clonedInput" + cloneIndex);
new_clone.find(".label-nbr").text(cloneIndex);
new_clone.find(".category").attr("id","category"+cloneIndex);
new_clone.find(".remove").attr("id","remove"+cloneIndex);
new_clone.on('click', 'button.clone', clone);
new_clone.on('click', 'button.remove', remove);
$(".clone").before(new_clone);
}
}
function remove(){
if(cloneIndex>1){
$(this).parents(".clonedInput").remove();
cloned_nbr--;
}
}
$("button.clone").on("click", clone);
$("button.remove").on("click", remove);
body { padding: 10px;}
.clonedInput { padding: 10px; border-radius: 5px; background-color: #def; margin-bottom: 10px; }
.clonedInput div { margin: 5px; }

</select>
</div>

我会将普通块初始化为模板并将其用作克隆基础。
