我有一个表单,我希望能够根据需要多次复制一组字段.而且我还想让那些新字段组的属性的字段id,名称和标签增加1.我到目前为止用jQuery尝试了这个,并且至少复制了字段组,但是删除了没有不行.而且我不确定如何为这3个属性中的每一个做1.我感谢任何帮助.
这是一个jsfiddle,它

JS
// Add a new repeating section
$('.addFight').click(function(){
var lastRepeatingGroup = $('.repeatingSection').last();
lastRepeatingGroup.clone().insertAfter(lastRepeatingGroup);
return false;
});
// Delete a repeating section
$('.deleteFight').click(function(){
$(this).parent('div').remove();
return false;
});
解决方法
这应该根据所有三个元素自动重命名：
// Add a new repeating section
$('.addFight').click(function(){
var currentCount = $('.repeatingSection').length;
var newCount = currentCount+1;
var lastRepeatingGroup = $('.repeatingSection').last();
var newSection = lastRepeatingGroup.clone();
newSection.insertAfter(lastRepeatingGroup);
newSection.find("input").each(function (index,input) {
input.id = input.id.replace("_" + currentCount,"_" + newCount);
input.name = input.name.replace("_" + currentCount,"_" + newCount);
});
newSection.find("label").each(function (index,label) {
var l = $(label);
l.attr('for',l.attr('for').replace("_" + currentCount,"_" + newCount));
});
return false;
});
// Delete a repeating section
$('.deleteFight').live('click',function(){
$(this).parent('div').remove();
return false;
});
我更改了删除处理程序,改为使用.live(),这样处理程序也会附加到该按钮的新创建副本.现在,如果你正在使用jquery> 1.7你应该使用.on()
on()版本将是：
// Delete a repeating section
$(document).on('click','.deleteFight',function(){
$(this).parent('div').remove();
return false;
});
