我试图让John Resig的jQuery Live Search与Quicksilver Style一起使用选择多表单控件.他的代码基于 John Nunemaker的工作开发他的quicksilver.js代码.
我遇到的问题是,在选择框中只有Firefox支持.hide()选项值,我无法找到适合IE,Safari,Opera和Chrome的方法.
这是一个例子,我已经列出了John R的代码,但你需要抓住quicksilver.js并自己在本地托管它.同样,这在Firefox中很有用,但对rows.hide()的调用在其他浏览器上没有任何作用.
我已经尝试将标签包装在div中并隐藏但没有运气.
有任何想法吗？

最好的方法是添加和删除DOM中的选项.
像这样:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#q').liveUpdate('#posts').focus();
});
jQuery.fn.liveUpdate = function(list){
list = jQuery(list);
if ( list.length ) {
// Changed 'li' to 'option' below
var rows = list.children('option'),
cache = rows.map(function(){
return this.innerHTML.toLowerCase();
});
var all = rows;
all.each(function(i){
$(this).attr("itext", this.innerHTML.toLowerCase());
});
this
.keyup(filter).keyup()
.parents('form').submit(function(){
return false;
});
}
return this;
function filter(){
var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = [];
if ( !term ) {
list.append(all);
} else {
rows.remove();
all.each(function(i){
var score = $(this).attr("itext").score(term);
if (score > 0) { scores.push([score, i]); }
});
jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){
list.append(all[this[1]]);
});
rows = list.children('option');
}
}
};
</script>
编辑:
需要在阵列"全部"而不是行上得分.
