我有这个ajax自动完成功能,可以在每个输入字段上使用.train类。但是,传递到.suggest_q类的建议显示在每个.suggest_q中,每个.train输入字段旁边,而不仅仅是正在使用的.train字段。我相信我正在使用正确的选择器,因为我在.click函数附近使用'this'而不是.train,但我仍然遇到问题。我希望此函数仅适用于用户正在使用的.suggest_q和.train类,并且其他类不显示任何建议。使用自动完成功能处理正在键入的.train和.suggest_a的最佳方法是什么?
这是我用于添加新.train输入字段的ajax代码:
<script type="text/javascript">
$(function() {
var scntDiv = $('#p_scents');
var i = $('#p_scents p').size() + 0;
$('#addScnt').live('click', function() {
$('<p><input type="text" name="train[]" autocomplete="off" class="train" /><span class="suggest_q" id="suggest_q"></span><a href="#" id="remScnt">Remove train</a></p>').appendTo(scntDiv);
i++;
return false;
});
$('#remScnt').live('click', function() {
if( i > 2 ) {
$(this).parents('p').remove();
i--;
}
return false;
});
});
</script>
这是ajax自动完成代码
<script type="text/javascript">
$(document).ready(function() {
$(".train").each(function(index, element) {
$(".train").live("keyup", function() {
$(".suggest_q").html("");
var train = $(this).val();
train = $.trim(train);
if(train)
{
$.ajax({
url: "train_ajax_query.php",
data: "train="+train,
success: function(msg) {
$(".suggest_q").html(msg);
$(".suggest_q ul li").mouseover(function() {
$(".suggest_q ul li").removeClass("hover");
$(this).addClass("hover");
})
$(".suggest_q ul li").click(function() {
var value = $(this).html();
$(element).val(value);
$(".suggest_q ul li").remove();
});
}
});
}
});
});
});
</script>
这是HTML
<div id="p_scents">
<input type="text" class="train" size="20" autocomplete="off" name="train[]" />
<div id="suggest_q" class="suggest_q">
</div>
</div>

在自动填充代码中,您使用全局选择器。您需要保存所选元素,然后使用这些变量。
//Changed the live call for an on call since live is deprecated.
$(document).ready(function() {
$("#p_scents").on("keyup", '.train', function() {
//we save vars with the objects we want to work with.
var selectedTrain = $(this);
var selectedSuggest = $(this).siblings('.suggest_q');
selectedSuggest.html("");
var train = selectedTrain.val();
train = $.trim(train);
if(train) {
$.ajax({
url: "train_ajax_query.php",
data: "train="+train,
success: function(msg) {
//the variables here should still be valid, unless you start more than one ajax
//call simultaneously.
selectedSuggest.html(msg);
selectedSuggest.find("ul li").mouseover(function() {
// This can happen when the variable selectedSuggest is no longer valid
//for example, when another try has been done on another .train
$(this).siblings("li").removeClass("hover");
$(this).addClass("hover");
});
selectedSuggest.find("ul li").click(function() {
var value = $(this).html();
//again, the vars can have changed here, since the click can be a long time
//after the event registration
$(this).parents('.suggest_q').siblings('input').val(value);
$(this).parents('.suggest_q').find("li").remove();
});
}
});
}
});
});
代码尚未经过测试,但应该可以使用。如果您发现任何错误,请留下评论,我将进行编辑。
