jquery对table中各数据的增加、保存、删除操作示例_jquery

添加按钮
代码如下:


table id是pswd_basic_fill_template
添加方法
代码如下:
function addRowForPswdBasicFillTemplate(tid){
var applyAreaOptionStr = $('#applyAreaOptionStr').val(); //这里是对select框的一些初始化
did = tid;
var tr = $("").attr("bgcolor","#FFFFFF");
tr.append($("").html(""));
tr.append($("").html(""));
tr.append($("").html(""));
tr.append($("").html(""));
tr.append($("").html(""+applyAreaOptionStr+""));
tr.append($("").html(""+$("#indexSpeciesHtml").val()+""));
tr.append($("").html("")); <BR>tr.append($("<td></td>").html("<input type='text' name='cap' id='cap' size='5'/>")); <BR>tr.append($("<td></td>").html("<input type='text' name='base_value' id='base_value' size='5'/>"));
