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> <table id="table1" border="1" cellpadding="0" cellspacing="0"> <tr> <th> <input type="checkbox" id="checkall" onclick="checkAll1(this)"/> </th> <th>姓名</th> <th>性别</th> <th>密码</th> <th>地址</th> </tr> <tr> <td> <input type="checkbox" id="Checkbox1" /> </td> <td>张三</td> <td>男</td> <td>zhangsan</td> <td>上海</td> </tr> <tr> <td> <input type="checkbox" id="Checkbox2" /> </td> <td>李四</td> <td>男</td> <td>lisi</td> <td>安庆</td> </tr> <tr> <td> <input type="checkbox" id="Checkbox3" /> </td> <td>王五</td> <td>男</td> <td>beijing</td> <td>北京</td> </tr> <tr> <td> <input type="checkbox" id="Checkbox4" /> </td> <td>无名氏</td> <td>女</td> <td>wumingshi</td> <td>上海</td> </tr> <tr> <td> <input type="checkbox" id="Checkbox5" /> </td> <td>赵老师</td> <td>男</td> <td>zhaolaoshi</td> <td>浙江</td> </tr> <tr> <td colspan="5" align="center"> <input type="button" id="btnAdd" runat="server" value="新增" onclick="btnAddRow()" /> <input type="button" id="btnDelete" runat="server" value="删除" onclick="btnDeleteRow()" /> <input type="button" id="btnSave" runat="server" value="保存" onclick="btnSaveClick()" /> </td> </tr> </table>
