Javascript 当另一个搜索是action';D

Javascript 当另一个搜索是action';D,javascript,jquery,Javascript,Jquery,我有一个搜索框,显示一个列表项,并在用户单击按钮后清除搜索字段…但是如果用户要再次搜索,我如何删除搜索项?因此,页面只显示新的搜索结果,而不显示以前的搜索结果 var noNameFound = true; var searchedStudent = []; // Stores names in an array where names can be pulled and shown when button is clicked var studentArr = []; $('.studen

我有一个搜索框,显示一个列表项,并在用户单击按钮后清除搜索字段…但是如果用户要再次搜索,我如何删除搜索项?因此,页面只显示新的搜索结果,而不显示以前的搜索结果

var noNameFound = true;
var searchedStudent = [];

// Stores names in an array where names can be pulled and shown when button is clicked
var studentArr = [];

$('.student-list').children().each(function(){
    studentArr.push(this);
});

// this will search through the array to locate the student.
$('.userSearch').on('click', function(){
    //stores users search into a variable
    var searchRequest = $('#search-input').val();

    //search through array here...
    for (var i = 0; i < studentArr.length; i++) {
        var studentstr = studentArr[i].innerText;

        if (studentstr.indexOf(searchRequest) !== -1) {

            console.log('YAY!! the name:: ' + searchRequest + ' ::is in our list');
            $(".student-list li").css("display","none"); // removes all students from the list.

            searchedStudent.push(studentArr[i]);
            $(searchedStudent).show(); // displayes the searched student.

            noNameFound = false;
        }

        $(".student-list").prepend(errorMessage);
        $('.student-item').css('display', 'none');

//这将在数组中搜索以定位学生。
$('.userSearch')。在('click',function()上{
//存储用户搜索到的变量
var searchRequest=$(“#搜索输入”).val();
//在这里搜索数组。。。
对于(变量i=0;i很抱歉,我们无法找到您要查找的名称,
请单击此处刷新页面,然后重试。

”; $(“.student list”).prepend(错误消息); $('.student item').css('display','none'); $('.refresh')。在('click',function()上{ location.reload(); }); } 如果(未找到){ //停止用户搜索空搜索字段。 $('.userSearch').prop('disabled',true); $(“#搜索输入”).keyup(函数(){ $('.userSearch').prop('disabled',this.value==“”?true:false); }); } });

这就是我到目前为止所做的

您需要在单击事件处理程序中的循环之前重置
searchedStudent
数组

// rest of the code

// this will search through the array to locate the student.
$('.userSearch').on('click', function(){
    //stores users search into a variable
    var searchRequest = $('#search-input').val();

    searchedStudent = []; // <<<<<<<<<<<<<<< HERE

    //search through array here...
    for (var i = 0; i < studentArr.length; i++) {
        var studentstr = studentArr[i].innerText;

// rest of the code
//代码的其余部分
//这将在数组中搜索以定位学生。
$('.userSearch')。在('click',function()上{
//存储用户搜索到的变量
var searchRequest=$(“#搜索输入”).val();

searchedStudent=[];//我需要更多的代码来查看,但我猜您不会在单击后删除数组,请尝试在$('.userSearch')之后添加。在('click',function()…searchedStudent=[];这是我的提琴,你需要在刚刚更新的alsosorry中添加html代码:这太简单了,我只需要在函数中声明数组。我能问一下为什么吗?我明白了。但是感谢你帮我解决了这个问题……非常感谢
