ASP.Net如何使用javascript我遍历网格中的所有行 [英] ASP.Net How can I iterate all rows in grid using javascript

问题描述

我有在电网计算的麻烦，我做的功能，但它只能在网格的第一行，并计算总格的第一行，然后显示总计文本这个值了。我想对所有的四行格一样，我该怎么办？请帮助。
        功能CalculateTotal（）{
                VAR Gtot = 0;

  VAR行数= 0;
            // VAR行数=的document.getElementById（'＆LT;％= hfGrdRows.ClientID％GT;'）值 -  0。
            //警报（行数）;
            VAR格=的document.getElementById（'＆LT;％= Grd_Exams.ClientID％GT;'）;
            对于（VAR I = 1; I＆LT; grid.rows.length;我++）{                    VAR电池= grid.rows [I] .cells;
                    // VAR HTML =电池[0] .innerHTML;                        VAR参与=的document.getElementById（'txtCl_Part'）值 -  0。                        。VAR Assgnmnt =的document.getElementById（'txtAssgnmnt'）值 -  0;
                        。VAR测验=的document.getElementById（'txtQuiz'）值 -  0;
                        VAR WrPaper =的document.getElementById（'txtWP'）值 -  0。
                        。VAR OSME =的document.getElementById（'txtOSME'）值 -  0;
                        //为（VAR I = 1; I＆LT; grdLength  -  1;我++）{                        无功总= parseFloat（参与）+ parseFloat（Assgnmnt）+ parseFloat（测验）+ parseFloat（WrPaper）+ parseFloat（OSME）;
                        如果（！isNaN（总计））{
                            。的document.getElementById（'txtTotal'）值=总;
                        }
                        其他{
                            警报（Nikal）;
                        }
                    }
                。VAR getTotal =的document.getElementById（'txtTotal'）值 -  0;
                VAR Gtot = parseInt函数（Gtot）+ parseFloat（getTotal）;
                如果（！isNaN（Gtot））{
                    。的document.getElementById（'txtGTot'）值= Gtot;
                }                其他{
                    警报（无法显示合计）;
                }                VAR百分比=（parseFloat（Gtot）* 100）/ 400;                如果（！isNaN（百分比））{
                    的document.getElementById（'txtPercent'）值=百分比。
                }
                其他{
                    警报（无法显示百分比）;
                }
        }
 

解决方案

GridView控件只是一个表

  VAR表=的document.getElementById（MYTABLE）;
 对于（VAR I = 0，排;排= table.rows [I];我++）{
 //行
 对于（VAR X = 0，列;西= row.cells [X]，X ++）{
 //柱和放大器;列单元格
  如果（X === 0）{
  //第一列
  VAR电池= row.cells [X];
 //做一些细胞
    }
  }
 }
 

i am having trouble in calculation in grid, i made function but it works only on 1st row of grid and calculate total of first row of grid and then show this value in grand total textbox too. I want to do the same on all 4 rows of grid, what do i do? Kindly help. function CalculateTotal() { var Gtot = 0;

            var RowCount = 0;
            //var RowCount = document.getElementById('<%= hfGrdRows.ClientID%>').value - 0;
            //alert(RowCount);
            var grid = document.getElementById('<%= Grd_Exams.ClientID%>');
            for (var i = 1; i < grid.rows.length ; i++) {

                    var cell = grid.rows[i].cells;
                    //var HTML = cell[0].innerHTML;

                        var Participation = document.getElementById('txtCl_Part').value - 0;

                        var Assgnmnt = document.getElementById('txtAssgnmnt').value - 0;
                        var Quiz = document.getElementById('txtQuiz').value - 0;
                        var WrPaper = document.getElementById('txtWP').value - 0;
                        var OSME = document.getElementById('txtOSME').value - 0;
                        //for (var i = 1; i < grdLength - 1; i++) {

                        var Total = parseFloat(Participation) + parseFloat(Assgnmnt) + parseFloat(Quiz) + parseFloat(WrPaper) + parseFloat(OSME);
                        if (!isNaN(Total)) {
                            document.getElementById('txtTotal').value = Total;
                        }
                        else {
                            alert("Nikal");
                        }
                    }
                var getTotal = document.getElementById('txtTotal').value - 0;
                var Gtot = parseInt(Gtot) + parseFloat(getTotal);
                if (!isNaN(Gtot)) {
                    document.getElementById('txtGTot').value = Gtot;
                }

                else {
                    alert("Cannot Show Total");
                }

                var Percentage = (parseFloat(Gtot) * 100) / 400;

                if (!isNaN(Percentage)) {
                    document.getElementById('txtPercent').value = Percentage;
                }
                else {
                    alert("Cannot show percentage");
                }
        }

解决方案

Gridview is just a table

var table = document.getElementById("mytable");
 for (var i = 0, row; row = table.rows[i]; i++) {
 //row
 for (var x = 0, col; col = row.cells[x]; x++) {
 // column & column cell
  if (x===0) {
  //first column
  var cell = row.cells[x];
 // do something with cell
    }
  }  
 }
