我正在尝试为现有div创建克隆div。克隆正在运行,并允许用户通过单击按钮克隆div。现在我想要验证的是,只允许用户克隆div最多6次,如果可能的话,显示消息"你不能再添加项目"
<div id ="specdiv ">
<fieldset class="fieldset">
<legend class="legend">Question Specification</legend>
<div class="editor-label">
@Html.LabelFor(model => model.OfferedAnswer)
</div>
<div class ="answerchoice1" id="">
<div class="editor-field">
@Html.TextAreaFor(model => model.OfferedAnswer.AnswerText)
</div>
</div>
</fieldset>
</div>
<button id="quesId" class="mini-button" type =" button">+</button>
$(document).ready(function () {
$('button').click(function () {
//$('.answerchoice1').before($('.answerchoice1').clone())
var $target = $('.answerchoice1').find('div.editor-field:first');
$target.clone().appendTo('.answerchoice1');
var tID = $(this).attr(".answerchoice1").split(/ _/);
//console.log($('.example-1').html());
})
})
答案 0 :(得分:1)
这样的事情就是你所追求的:
$(document).ready(function () {
$('button').click(function () {
if($('.editor-field').length >= 6){
alert('No more than 6!');
return false;
}
//$('.answerchoice1').before($('.answerchoice1').clone())
var $target = $('.answerchoice1').find('div.editor-field:first');
$target.clone().appendTo('.answerchoice1');
var tID = $(this).attr(".answerchoice1").split(/ _/);
//console.log($('.example-1').html());
})
})
