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='checkbox']");
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='checkbox']");
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='checkbox']").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)
{
$("#table1 tr").find("input[type='checkbox']").attr("checked",evt.checked);
}11. The client dynamically adds rows , Delete the line
function btnAddRow()
{
//行号是从0开始，最后一行是新增、删除、保存按钮行 故减去2
var rownum=$("#table1 tr").length-2;
var chk="<input type='checkbox' id='chk_"+rownum+"' name='chk_"+rownum+"'/>";
var text="<input type='text' id='txt_"+rownum+"' name='txt_"+rownum+"' width='75px'/>";
var sel="<select id='sel_"+rownum+"'><option value='1'>男</option><option value='0'>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()
{
$("#table1 tr").find("input[type='checkbox']").each(function(i){
if($(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='checkbox']");
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='text']" || "select").each(function(i){
//alert($(this).val());
//});
$("#table1 tr").find("td").each(function(i){
if($(this).find("input[type='text']").length>0)
{
alert($(this).find("input[type='text']").val());
}
else if($(this).find("select").length>0)
{
alert($(this).find("select").val());
}
});
}<style type="text/css">
.hover
{
background-color:red;
}
</style>
