JQuery undefined不是一个函数 [英] JQuery undefined is not a function

问题描述

我在网格中使用jquery进行计算都做得很好而不是当它是总转弯jquery时抛出错误未捕获的TypeError：undefined不是函数在这一行$（[id * = txtTotal]） .live（keyup，function（）{，请给我建议。

i use jquery for calculation in grid all done well instead that when it is grand total turn jquery throw an error "Uncaught TypeError: undefined is not a function" at this line " $("[id*=txtTotal]").live("keyup", function () {", kindly give me suggestion.

function CalculateTotal(select) {

                var row = $(select).closest("tr");
                var ClPart = $("[id*=txtCl_Part]", row).val();
                //alert(ClPart.toString());
                var Assgnmnt = $("[id*=txtAssgnmnt]", row).val();
                //alert(Assgnmnt.toString());
                var Quiz = $("[id*=txtQuiz]", row).val();
                //alert(Quiz.toString());
                var WrPaper = $("[id*=txtWP]", row).val();
                //alert(WrPaper.toString());
                var OSME = $("[id*=txtOSME]", row).val();
                //alert(OSME.toString());
                var Total = (parseFloat(ClPart.valueOf()) + parseFloat(Assgnmnt.valueOf()) + parseFloat(Quiz.valueOf()) + parseFloat(WrPaper.valueOf()) + parseFloat(OSME.valueOf()));
                //   alert(Amount.toString());

                $("[id*=txtTotal]", row).val(Total.valueOf());
            }

            $("[id*=txtTotal]").live("keyup", function () {
		                    
			"Error comes at above line"

		var Gtot = 0;
                    var percent = 0.0;
                    $("[id*=txtTotal]").each(function (index) {
                        //Check if number is not empty
                        if ($.trim($(this).val()) != "")
                        //Check if number is a valid Float
                            if (!isNaN($(this).val()))
                                Gtot = Gtot + parseFloat($(this).val());
                        percent = (parseFloat(Gtot) * 100) / 400;
                    });

                    $("[id*=txtGTot]").val(Gtot.valueOf());
                    $("[id*=txtPercent]").val(percent.valueOf());

                });

推荐答案

（[id * = txtTotal]）。live（keyup ，function（）{，请给我建议。

("[id*=txtTotal]").live("keyup", function () {", kindly give me suggestion.

function CalculateTotal(select) {

                var row =

（select）.closest（< span class =code-string> tr）;
var ClPart =

(select).closest("tr"); var ClPart =

（ [id * = txtCl_Part]，row）.val（）;
// alert（ClPart.toString（））;
var Assgnmnt =

("[id*=txtCl_Part]", row).val(); //alert(ClPart.toString()); var Assgnmnt =
