我已使用jQuery
实施了搜索框。这是发送搜索词和的代码
之后,我收到Json
,我用它来列出匹配的搜索项目。
问题是每个keyup
我删除所有匹配的项目:
$("#realPlaceForSearchItems").html("");
因为如果我不这样做,那么当我输入“专业”然后输入“ d ”时,我会在搜索产品时遇到重复。 (我将列表项追加到列表中)是否有可能实现我以某种方式删除与“ prod ”(之前与“ pro ”匹配的元素并且在输入“ d ”后,与prod匹配的元素保持不变。
$("#searchInput").keyup(function () {
$this = $(this);
$('#realPlaceForSearchItems').show();
$("#realPlaceForSearchItems").html("");
var seachedTerm=$this.val();
if ($this.val().length> 2)
{
$("#realPlaceForSearchItems").html("");
$('#realPlaceForSearchItems').show();
$.ajax({
type: "POST",
url: ROOT + "Filter/Search/",
data: {term: $this.val()},
success: function (data)
{
var Link = $("#searchTemplate>li>a");
var placeForProductId=$("#searchTemplate>li>a>input");
var placeForPicture = $("#searchTemplate>li>a>div>img");
var placeForProductName = $("#searchTemplate>li>a>div>div");
var placeForPrice= $("#searchTemplate>li>a>div>span");
$.each(data.productsWereSeached, function () {
console.log("sddsd", data.totalrows);
var imagesFolder="/Content/images/";
var pathToProduct="/ProductDetails/Index/"
var slash = "/";
Link.attr("href", pathToProduct + this.Id);
placeForProductId.val(this.Id);
if (this && this.Picture) //for the case there is no any picture there would be error cant read propery or undefined
placeForPicture.attr("src", imagesFolder + this.Id + slash + this.Picture.FileName);
else
placeForPicture.attr("src", "");
placeForProductName.html(this.Name);
placeForPrice.html((parseFloat(this.Price) / 100.0).toString() + " kn");
$listItem = $("#searchTemplate").html();
$("#realPlaceForSearchItems").append($listItem);
});
$("#nOfMatchedProducts").val(data.totalrows);
if (data.totalrows > 2)
{
var searchurl="/Search/ShowMoreSearched?term="
$showMoreItem = $("#showMoreItem").html();
$("#showMoreItem>li>a").attr("href",searchurl+seachedTerm);
$("#realPlaceForSearchItems").append($showMoreItem);
}
},
failure: function ()
{
}
});
}
});

$.each(data.productsWereSeached, function () {
if($('a[href="'+pathToProduct + this.Id+'"]').length == 0) {
console.log("sddsd", data.totalrows);
var imagesFolder="/Content/images/";
var pathToProduct="/ProductDetails/Index/"
var slash = "/";
Link.attr("href", pathToProduct + this.Id);

Psst ...我假设你也想限制对服务器的调用,而你的搜索结果列表并不是很大!
原来如此!您当前的方法的好处是您不必管理/比较任何现有数据集。当搜索“pro”更改为搜索“cro”或任何其他使先前的AJAX调用无关的更改时,这会使事情变得更容易。但是,就像你说的那样,当你在“专业”之后搜索“prod”时,它会让你明白清楚,然后重新添加项目效率低下。
点子:

将$ .each(http://api.jquery.com/jQuery.each/)中的索引传递到您的函数中,然后使用它来选择 replaceWith 的搜索结果({{3你刚刚构建的元素。在使用此方法时,搜索结果UL中的四个LI元素必须在执行search.keyup之前存在。
通过改变两行来做到这一点......
$.each(data.productsWereSeached, function (index) {
... all of the existing code in the loop stays the same except ...
$("#realPlaceForSearchItems LI:eq(" + index + ")").replaceWith($listItem);
});
