jQuery:如何克隆自动完成字段? [英] JQuery: How to clone autocomplete fields?
问题描述
我正在使用JörnZaefferer的jquery自动完成插件，并且在克隆自动完成字段时似乎无法弄清楚如何使其工作.几乎可以用，因为当我键入文本时，克隆的自动完成字段会显示选择，但我不能选择项目.起初我以为这是浏览器兼容性问题，但是在FF3和Safari中都发生过，所以我猜我错过了一个陷阱.
I am using Jörn Zaefferer's jquery autocomplete plugin, and I can't seem to figure out how to make it work when I clone an autocomplete field. It almost works, in that the cloned autocomplete field displays the choices when the I type in text, but I cannot select items. At first I thought it was a browser-compatibility issue, but it happens in both FF3 and Safari, so I'm guessing there's a gotcha I've missed.
以下是我正在做的工作示例:
Here is a working example of what I'm doing:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>Autocomplete Clone Demo</title>
<style>
body {
margin: 40px;
}
.hide_element {
display: none;
}
</style>
<link rel="stylesheet" href="http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.css" type="text/css" />
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.js"></script>
<script type="text/javascript">
function setAutocomplete()
{
var users = [
{ name: "Fred", id: "1" },
{ name: "Barney", id: "2" },
{ name: "Wilma", id: "3" }
];
$(".user_selector").autocomplete(users,
{
mustMatch: true,
matchContains: true,
minChars: 2,
formatResult: function(row) { return row.name; },
formatItem: function(row, i, max) { return row.name; }
}
);
}
var current= 0;
var addParticipantFields = function()
{
current++;
$newParticipant = $("#template").clone(true);
$newParticipant.removeAttr("id");
$newParticipant.removeClass("hide_element");
$prefix = "extra" + current;
$newParticipant.children("div").children(":input").each(function(i) {
var $currentElem= $(this);
$currentElem.attr("name",$prefix+$currentElem.attr("name"));
});
$newParticipant.appendTo("#participantsField");
setAutocomplete();
}
$(document).ready(function() {
setAutocomplete();
$("#addParticipant").live("click", addParticipantFields);
});
</script>
</head>
<body>
<h1>Test Autocomplete Cloning</h1>
<form id="demo" method="post" action="">
<fieldset id="participantsField">
<label>Participants</label>
<div class="participant">
<input class="user_selector" name="user" size="30"/>
</div>
</fieldset>
<!-- This is the template for adding extra participants -->
<div class="participant hide_element" id="template">
<input class="user_selector" name="_user" size="30"/>
</div>
<p><input type="button" id="addParticipant" value="Add Another Participant"></p>
<p><input class="button" type="submit" value="Submit"/></p>
</form>
</body>
</html>
推荐答案
制作
$newParticipant = $("#template").clone(true);
像这样
$newParticipant = $("#template").clone();
当您未在#template上克隆事件时，您的示例在FF中对我有用.
Your example works for me in FF when you don't clone events on #template.
