我必须创建3个输入文本框,以获取有关姓名和电子邮件地址的用户输入。 我必须动态创建它, 即 ,因为用户点击了电子邮件输入字段,应该创建所有三个元素的新行。 这是包含3个输入的一行的代码:
<div class='row' id="inputcontainer">
<div class="form-group clearfix" >
<div class="col-md-2 col-md-offset-2">
<div class="form-text-field first-name">
<label>First name</label>
<input type="text" id="firstName10" class="signup-input" name="" placeholder="">
</div>
</div>
<div class="col-md-2">
<div class="form-text-field last-name">
<label>Last name</label>
<input type="text" id="lastName0" class="signup-input" name="" placeholder="optional">
</div>
</div>
<div class="col-md-4">
<div class="form-text-field email">
<div>
<label>Email</label>
<input type="text" data-index="0" id="inputMail0" class="signup-input text-value " name="email[0]" placeholder="e.g. example@url.com"/>
<span class="common-sprite disNone sign-up-cross first"></span>
</div>
</div>
</div>
</div>
</div>
如何动态创建它?
我使用以下代码进行克隆,并将其克隆几次而不是1
maxIndex = 0;
$('form').on('input','.email',function(){
$(this).parent().find('.common-sprite').removeClass('disNone');
var lastmail = $(this); if(($(this).val().length > 0)&&(lastmail.data('index') == maxIndex)) {
var count = $('.row.inputcontainer').length;
console.log(count);
maxIndex++;
var clone = $('#template').clone(true).attr('id', '');
clone.find('.firstName[id=firstName'+(maxIndex-1)+']').attr('id', 'firstName' + maxIndex).attr('name', 'first[' + maxIndex +']').addClass('signup-input firstName').val('');
clone.find('.lastName[id=lastName'+(maxIndex-1)+']').attr('id', 'lastName' + maxIndex).attr('name', 'last[' + maxIndex +']').addClass('signup-input lastName').val('');
clone.find('.email[id=inputMail'+(maxIndex-1)+']').attr('id', 'inputMail' + maxIndex).attr('name', 'email[' + maxIndex +']').data('index', maxIndex).addClass('signup-input text-value email').val('');
$('.inputcontainer').append(clone);
}

.blur()
来触发动态添加,这样如果您在电子邮件输入中键入内容并单击其外部,则会显示接下来的3行信息。我还添加了一些类来帮助jquery更快更可靠地查找元素。我每次使用clone()
重新创建3行的相同结构。
$(document).ready(function() {
$('.email').on('blur', function() {
if($(this).val().length > 0) {
var count = $('.row').length;
console.log(count);
var clone = $('#template').clone(true).attr('id', '');
clone.find('.firstName').attr('id', 'firstName' + count).val('');
clone.find('.lastName').attr('id', 'lastName' + count).val('');
clone.find('.email').attr('id', 'inputMail' + count).val('');
$('body').append(clone);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='row inputcontainer' id="template">
<div class="form-group clearfix" >
<div class="col-md-2 col-md-offset-2">
<div class="form-text-field first-name">
<label>First name</label>
<input type="text" id="firstName0" class="signup-input firstName" name="" placeholder=""/>
</div>
</div>
<div class="col-md-2">
<div class="form-text-field last-name">
<label>Last name</label>
<input type="text" id="lastName0" class="signup-input lastName" name="" placeholder="optional"/>
</div>
</div>
<div class="col-md-4">
<div class="form-text-field email">
<div>
<label>Email</label>
<input type="text" data-index="0" id="inputMail0" class="signup-input text-value email" name="email[0]" placeholder="e.g. example@url.com"/>
<span class="common-sprite disNone sign-up-cross first"></span>
</div>
</div>
</div>
</div>
</div>
希望这有帮助!

这是否与您想要的相似?
$(document).on("blur",".add",function()
{
$("#inputcontainer").append("<br />");
$("#inputcontainer").append("First Name <input type='text' class='signup-input' name='' placeholder='' /><br />");
$("#inputcontainer").append("last Name <input type='text' class='signup-input' name='' placeholder='optional' /><br />");
$("#inputcontainer").append("Email Address <input type='text' data-index='0' class='signup-input text-value add' name='email[0]' placeholder='e.g. example@url.com' /><br />");
});

键入电子邮件文本框,然后离开以创建新文本框。
