Question

我有一个gridview，其中包含2个带复选框的coulmns。我有一个标题列，其复选框名为Approve all，另一个名为Reject all。当我单击其中一个复选框时，将检查该gridview中存在的所有子复选框，但我只想检查特定列复选框。请帮忙：

<script type="text/javascript" language="javascript">
    function checkAll(objRef) {
    var GridView = objRef.parentNode.parentNode.parentNode;
    var inputList = GridView.getElementsByTagName("input");

    for (var i = 0; i < inputList.length; i++) {
        var row = inputList[i].parentNode.parentNode;

            if (inputList[i].type == "checkbox" && objRef != inputList[i]) {
                if (objRef.checked) {
                    row.style.backgroundColor = "#c3d9ff";
                    inputList[i].checked = true;
                }
                else {
                    if (row.rowIndex % 2 == 0) {
                        row.style.backgroundColor = "#c3d9ff";
                    }
                    else {
                        row.style.backgroundColor = "white";
                    }

                    inputList[i].checked = false;
                }
            }
        }
    }
</script>

        </asp:TemplateField>
    </Columns>                   
</asp:GridView>

使用jquery来解决可能会减少时间的此类问题

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">
</script>
<script type="text/javascript">
    function checkAll(data) {
        $('[id$=checkAll]').click(function() {
            $("[id$='CheckApprove']").attr('checked', true);
        });     
        $('[id$=RejAll]').click(function() {
            $("[id$='CheckReject']").attr('checked', false);
        });
    }
</script>
