$("#search-criteria").on("keyup", function() {
var g = $(this).val();
$(".fbbox .fix label").each( function() {
var s = $(this).text();
if (s.indexOf(g)!=-1) {
$(this).parent().parent().show();
}
else {
$(this).parent().parent().hide();
}
});
});?
or Better Way:
或更好的方法:
$("#search-criteria").on("keyup", function() {
var g = $(this).val().toLowerCase();
$(".fbbox .fix label").each(function() {
var s = $(this).text().toLowerCase();
$(this).closest('.fbbox')[ s.indexOf(g) !== -1 ? 'show' : 'hide' ]();
});
});?

Use Jquery
使用jQuery
? $(document).ready(function(){
var search = $("#search-criteria");
var items = $(".fbbox");
$("#search").on("click", function(e){
var v = search.val().toLowerCase();
if(v == "") {
items.show();
return;
}
$.each(items, function(){
var it = $(this);
var lb = it.find("label").text().toLowerCase();
if(lb.indexOf(v) == -1)
it.hide();
});
});
});?

Maybe use indexOf method:
也许使用 indexOf 方法:
var text ="some name";
var search = "some";
if (text.indexOf(search)!=-1) {
// do someting with found item
}

You can use regular expression instead of indexOfas it may not work in IE7/IE8
and using regular expression you will can also use the 'i' modifier to make the search case insensitive.
您可以使用正则表达式,indexOf因为它在 IE7/IE8 中可能不起作用,并且使用正则表达式您还可以使用 'i' 修饰符使搜索不区分大小写。
