Summary of jQuery operation Table methods

This time I will bring you a summary of the jQuery operation table method. What are the precautions for jQuery operation table. The following is a practical case, let's take a look.

1. The row changes color when the mouse moves

Method 1: hover(fun(), fun()) method in jQuery, parameter 1: first method Is to add the style function, parameter two: The second method is to cancel the style function

$("#table1 tr").hover(function(){
$(this).children("td").addClass("hover")
},function(){
$(this).children("td").removeClass("hover")
})

Method two:

$("#table1 tr:gt(0)").hover(function() {
$(this).children("td").addClass("hover");
}, function() {
$(this).children("td").removeClass("hover");
});

2. Odd and even rows have different colors

$("#table1 tbody tr:odd").css("background-color", "#bbf");
$("#table1 tbody tr:even").css("background-color","#ffc");
$("#table1 tbody tr:odd").addClass("odd")
$("#table1 tbody tr:even").addClass("even")

3.Hide a row

$("#table1 tbody tr:eq(3)").hide();

4.Hide a column

Method 1:

$("#table1 tr td::nth-child(3)").hide();

Method 2:

$("#table1 tr").each(function(){$("td:eq(3)",this).hide()});

5. Delete a row

//删除除第一行外的所有行
$("#table1 tr:not(:first)").remove();
//删除指定行
$("#table1 tr:eq(3)").remove();

#6. Delete a column

//删除除第一列外的所有列
$("#table1 tr th:not(:nth-child(1))").remove();
$("#table1 tr td:not(:nth-child(1))").remove();
//删除第一列
$("#table1 tr td::nth-child(1)").remove();

7. Get (set) the value of a certain cell

//设置table1,第2个tr的第一个td的值。
$("#table1 tr:eq(1) td:nth-child(1)").html("value");
//获取table1,第2个tr的第一个td的值。
$("#table1 tr:eq(1) td:nth-child(1)").html();

8. Insert a row:

//在第二个tr后插入一行
$("<tr><td>插入3</td><td>插入</td><td>插入</td><td>插入</td></tr>").insertAfter($("#table7 tr:eq(1)"));

9, Get the value of the specified cell in each row

var arr = [];
$("#table1 tr td:nth-child(1)").each(function (key, value) {
arr.push($(this).html());
});
var result = arr.join(',');

10. Select all or none

//方法一：
//全选或全不选 此传入的参数为event 如：checkAll(event)
function checkAll(evt)
{
 evt=evt?evt:window.event;
 var chall=evt.target?evt.target:evt.srcElement;
 var tbl=$("#table1");
 var trlist=tbl.find("tr");
 for(var i=1;i<trlist.length;i++)
 {
 var tr=$(trlist[i]);
 var input=tr.find("INPUT[type=&#39;checkbox&#39;]");
 input.attr("checked",chall.checked);
 }
}
//方法二：
//全选或全不选 此传入的参数为this 如：checkAll(this)
function checkAll(evt)
{
var tbl=$("#table1");
var trlist=tbl.find("tr");
for(var i=1;i<trlist.length;i++)
{
var tr=$(trlist[i]);
var input=tr.find("INPUT[type=&#39;checkbox&#39;]");
input.attr("checked",evt.checked);
}
}
//方法三：
//全选或全不选 此传入的参数为this 如：checkAll(this)
function checkAll(evt)
{
$("#table1 tr").find("input[type=&#39;checkbox&#39;]").each(function(i){
$(this).attr("checked",evt.checked)
});
}
//方法四：
//全选或全不选 此传入的参数为this 如：checkAll(this)
function checkAll(evt)
{
$("#table1 tr").find("input[type=&#39;checkbox&#39;]").attr("checked",evt.checked);
}

11. The client dynamically adds rows , Delete the line

function btnAddRow()
{
//行号是从0开始，最后一行是新增、删除、保存按钮行 故减去2
var rownum=$("#table1 tr").length-2;
var chk="<input type=&#39;checkbox&#39; id=&#39;chk_"+rownum+"&#39; name=&#39;chk_"+rownum+"&#39;/>";
var text="<input type=&#39;text&#39; id=&#39;txt_"+rownum+"&#39; name=&#39;txt_"+rownum+"&#39; width=&#39;75px&#39;/>";
var sel="<select id=&#39;sel_"+rownum+"&#39;><option value=&#39;1&#39;>男</option><option value=&#39;0&#39;>女</option></select>";
var row="<tr><td>"+chk+"</td><td>"+text+"</td><td>"+sel+"</td><td>"+text+"</td><td>"+text+"</td></tr>";
$(row).insertAfter($("#table1 tr:eq("+rownum+")"));
}
//客户端删除一行
//每次只能删除一行，删除多行时出错
function btnDeleteRow()
{
$("#table1 tr").find("input[type=&#39;checkbox&#39;]").each(function(i){
if($(this).attr("checked"))
{
if(i!=0)//不能删除行标题
{
$("#table1 tr:eq("+i+")").remove();
}
}
});
}
//这个比上面的要好，可以一下删除多个记录
function btnDeleteRow()
{
$("#table1 tr").each(function(i){
var chk=$(this).find("input[type=&#39;checkbox&#39;]");
if(chk.attr("id")!="checkall")//不能删除标题行
{
if(chk.attr("checked"))
{
$(this).remove();
}
}
});
}
//客户端保存
function btnSaveClick()
{
//find()方法中我暂时不知道如何设定多个筛选条件，所以下面得不到select列表的值
//$("#table1 tr td").find("input[type=&#39;text&#39;]" || "select").each(function(i){
//alert($(this).val());
//});
$("#table1 tr").find("td").each(function(i){
if($(this).find("input[type=&#39;text&#39;]").length>0)
{
alert($(this).find("input[type=&#39;text&#39;]").val());
}
else if($(this).find("select").length>0)
{
alert($(this).find("select").val());
}
});
}
