我有一个表单,我想设置它,以便当用户在输入中输入/选择值并单击“添加”按钮时,它将克隆每个输入/选择框,将它们分配给变量然后将它们附加到下面的另一个元素。我目前所拥有的只是返回[object Object]
而不是克隆元素。我哪里错了?
$(function() {
$('button').click(function() {
var $name = $('#name').clone(),
$email = $('#email').clone(),
$package = $('#package').clone(),
$newRow = '<div class="name">' + $name + '</div><div class="email">' + $email + '</div><div class="package">' + $package + '</div>';
$('.row').append($newRow);
});
});
.row {
display:table-row;
}
.row > div {
display:table-cell;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="name" />
<input id="email" />
<select id="package">
<option value="one">Package One</option>
<option value="two">Package Two</option>
<option value="three">Package Three</option>
</select>
<button>ADD ROW</button>
<div class="row">
</div>

您只需要附加克隆的对象。
$(function() {
$('button').click(function() {
var $name = $('#name').clone(),
$email = $('#email').clone(),
$package = $('#package').clone();
$('.row').append($name);
$('.row').append($email);
$('.row').append($package);
});
});
&#13;
.row {
display:table-row;
}
.row > div {
display:table-cell;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="name" />
<input id="email" />
<select id="package">
<option value="one">Package One</option>
<option value="two">Package Two</option>
<option value="three">Package Three</option>
</select>
<button>ADD ROW</button>
<div class="row">
</div>

将每个克隆元素附加到自己的div。然后将所有div添加到行中。
Due to a bug,您必须在克隆的选择框上强制值
$(function() {
$('button').click(function() {
var $name = $('<div class="name"></div>').append($('#name').clone()),
$email = $('<div class="email"></div>').append($('#email').clone()),
$package = $('<div class="package"></div>').append($('#package').clone());
$package.find('#package').val($('#package').val());
$('.row').append($name, $email, $package);
});
});
&#13;
.row {
display:table-row;
}
.row > div {
display:table-cell;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="name" />
<input id="email" />
<select id="package">
<option value="one">Package One</option>
<option value="two">Package Two</option>
<option value="three">Package Three</option>
</select>
<button>ADD ROW</button>
<div class="row">
</div>
&#13;
最后一件事。您不应该通过id=
识别元素,因为这些元素在整个页面中都是唯一的。尝试重写代码,以便可以使用选择器类。例如:
<input class="i_name" />
...
$('.i_name').clone()

我不完全明白你需要什么,但是克隆返回一个对象,这就是为什么追加到字符串将返回到[object Object]的原因。也许你可以使用outerHTML。
$(function() {
$('button').click(function() {
var $name = $('#name').clone();
$email = $('#email').clone();
$package = $('#package').clone();
$newRow = '<div class="name">' + $name[0].outerHTML + '</div><div class="email">' + $email[0].outerHTML + '</div><div class="package">' + $package[0].outerHTML + '</div>';
$('.row').append($newRow);
});
});
&#13;
.row {
display:table-row;
}
.row > div {
display:table-cell;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="name" />
<input id="email" />
<select id="package">
<option value="one">Package One</option>
<option value="two">Package Two</option>
<option value="three">Package Three</option>
</select>
<button>ADD ROW</button>
<div class="row">
</div>
