我如何遍历JavaScript中的gridview并检查复选框是否已选中 [英] How can I iterate through a gridview in javascript and check if the checkbox is checked or not

问题描述

function ComparePopup(gridName, value) {
        var myGrid = document.getElementById("<%= gridviewSearchResult.ClientID %>");
        var oRows = myGrid.rows;
        var rawDataRows = new Array();
        var hdncounter = document.getElementById("<%= hdnCounter.ClientID %>");
        var hdncount = document.getElementById("<%= hidCounter.ClientID %>");
        var cell;
        var j;
        for (var i = 0; i < oRows.length; i++) {
            var oRow = oRows[i];
           // for (var j = 0; j < oRows.cells.length; j++) {
            alert(myGrid.rows(i).cells(0).textContent);
//            if (oRow.getCell(0).getValue() == "true") {
//                j = j + 1;
//            }
       // }
     }

        if (hdncounter != "") {
            var counter = parseInt(hdncounter.value);
            hdncount.value = j + counter;

        }
        else {
            hdncount.value = j;
        }
        if (hdncount.value > 3) {
            var res = confirm("Since you have selected more than 3 profiles, their profiles will be exported to excel for comparison.");
            if (res != true)
                return false;
            else
                return true;
        }
    }

function ComparePopup(gridName, value) {
    var myGrid = document.getElementById("<%= gridviewSearchResult.ClientID %>");
    var oRows = myGrid.rows;
    var rawDataRows = new Array();
    var inps = myGrid.getElementsByTagName("input");
    var hdncounter = document.getElementById("<%= hdnCounter.ClientID %>");
    var hdncount = document.getElementById("<%= hidCounter.ClientID %>");
    var cell;
    var j=0;
    for (var i = 0; i < oRows.length; i++) {
        var oRow = oRows[i];
        if (myGrid.rows(i).cells(0).children[0] != null && myGrid.rows(i).cells(0).children[0].checked == true) {
            j = j + 1;
        }
    }
    if (hdncounter != "") {
        var counter = parseInt(hdncounter.value);
        hdncount.value = j + counter;

    }
    else {
        hdncount.value = j;
    }
    if (hdncount.value > 3) {
        var res = confirm("Since you have selected more than 3 profiles, their profiles will be exported to excel for comparison.");
        if (res != true)
            return false;
        else
            return true;
