jQuery遍历Table tr td td中包含标签

 function shengchen() {

             var arrTR = $("#tbModule").children();

             var Context="";

             $("#tbModule").find("tr").each(function () {

                 var arrtd = $(this).children();

                 tdContext = $.trim(arrtd.eq(0).text());

                 tdContext += ":" + arrtd.eq(2).find("input").val() + ";";

                 Context += tdContext;

             })

             Context= Context.substring(Context.indexOf(";")+1);

             $("#txtContent").val(Context);

         }

 


我这里是通过点击 来获取 table中的td的数据,其中一个td包含一个input标签

通过

$("#tbModule").find("tr").each(function () {})

来获回去所有行的对象,通过

$(this).children();

来获取行内所有的td,通过

arrtd.eq(0)

来获取某个制定的td,这里你也可以用循环来获取数据,注释的部分是获取td中标签的值

                 for (var k = 0; k < arrtd.length; k++) {

                     var con = arrtd.eq(k).text();

                     //var con = arrtd.eq(2).find("input").val();

                }
