本文实例讲述了jQuery实现模糊搜索功能的方法。分享给大家供大家参考,具体如下:
功能一:关键字搜索
总结:
1、搜索出的结果,前台先要清空原有表格
$("#tbody").empty;
2、后台返回的json格式字符串 js eval 专成对象
var stus = eval("(" + msg + ")");
在循环进行字符串拼接到表格上
$("#tbody").html(str);
$("#btn").click(function() {
var id = $.trim($("#id").val());
var classname = $.trim($("#classname").val());
var clazz = $.trim($("#class").val());
if (id == "" & classname == "" & clazz == "") {
alert("请至少输入一个筛选条件");
} else {
$.ajax({
type : "post",
url : "SearchServlet",
data : {
"type" : "find",
"id" : id,
"classname" : classname,
"class" : clazz
},
success : function(msg) {
if ("无结果" == msg) {
alert(msg);
$("#id").val("");
$("#classname").val("");
$("#class").val("");
}
var stus = eval("(" + msg + ")");
$("#tbody").empty;
var str = "";
for (var i = 0; i < stus.length; i++) {
str = str + "<tr><td>" + stus[i].id + "</td>"
str = str + "<td>" + stus[i].studentNo + "</td>"
str = str + "<td>" + stus[i].studentName + "</td>"
str = str + "<td>" + stus[i].studentClass + "</td>"
str = str + "<td>" + "<a href='javascript:a(" + stus[i].id + ")'>" + "删除" + "</a>" + "</td></tr>"
}
$("#tbody").html(str);
}
}
);
}
});
功能二:input框删除关键字,动态显示所有结果
总结:
1、a标签动态传参,传给后台进行删除,使用字符串拼接
str = str + "<td>" + "<a href='javascript:a(" + stus[i].id + ")'>" + "删除" + "</a>" + "</td></tr>"
$(".input").on('input', function(e) {
var id = $.trim($("#id").val());
var classname = $.trim($("#classname").val());
var clazz = $.trim($("#class").val());
if (id == "" && classname == "" && clazz == "") {
$.ajax({
type : "post",
url : "SearchServlet",
data : {
"type" : "all",
},
success : function(msg) {
var stus = eval("(" + msg + ")");
$("#tbody").empty;
var str = "";
for (var i = 0; i < stus.length; i++) {
str = str + "<tr><td>" + stus[i].id + "</td>"
str = str + "<td>" + stus[i].studentNo + "</td>"
str = str + "<td>" + stus[i].studentName + "</td>"
str = str + "<td>" + stus[i].studentClass + "</td>"
str = str + "<td>" + "<a href='javascript:a(" + stus[i].id + ")'>" + "删除" + "</a>" + "</td></tr>"
}
$("#tbody").html(str);
}
}
);
}
});
功能三:删除 table中的数据
总结:
在a标签里面传参 js写在a标签里面的两种方式
<td><ahref="javascript:a(${stu.id})" rel="external nofollow" >删除</a></td>
<td><a href="javascript:void(0);" rel="external nofollow" onclick="remove(${stu.id })">删除</a></td>
function a(id) {
$.ajax({
type : "get",
url : "SearchServlet?type=delete&id=" + id,
success : function(msg) {
alert(msg);
if ("删除成功" == msg) {
$("tr").remove("#stu_" + id);
}
}
});
}
