我已经使用jQuery
. 这是发送搜索词的代码,之后我收到Json
用于制作匹配搜索项目列表的代码。
问题是每次keyup
我删除所有匹配的项目:
$("#realPlaceForSearchItems").html("");
因为如果我不输入“ pro ”然后输入“ d ”,我会在搜索产品时得到重复。(我正在将列表项附加到列表中)是否有可能以某种方式删除与“ prod ”不匹配的元素(当然之前与“ prod ”匹配)并且匹配 prod 的元素在键入“ d ”后保持不变.
$("#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 ()
{
}
});
}
});
