var windowUrl = "about:blank";
var uniqueName = new Date();
var windowName = "Print" + uniqueName.getTime();
var printWindow = window.open(windowUrl, windowName, "left=50000,top=50000,width=0,height=0");

function HidColumn() {
// col_num = document.getElementById("Button").value;
rows = document.getElementById("<%= GV1.ClientID %>").rows;
for (i = 0; i < rows.length; i++) {
rows[i].cells[8].style.display = "none";
}
for (j = 0; j < rows.length; j++) {
rows[j].cells[9].style.display = "none";
}
}
// change logic to suit taste
function clicked() {
var b = HidColumn();
if (b)
printform()
return b;
}
<asp:ImageButton ID="ImageButton2" runat="server" ImageAlign="Right" ImageUrl="images/printer.jpg"
Style="margin-left: 5px; margin-right: 15px" OnClick="ImageButton2_Click" Width="36px"
OnClientClick="return clicked()" Visible="false" />
但是,当我单击ImageButton时,没有发生任何事情
这一行没有意义:var b = HidColumn();
函数HidColumn不返回任何内容。
AS我说过我同意steve的答案,您应该修改函数HidColumn以返回true或false。还有一点我想提一下,如果您从clicked((返回false,那么postback
将不会发生,否则它将调用服务器上的ImageButton2_Click
事件。
function HidColumn() {
// col_num = document.getElementById("Button").value;
rows = document.getElementById("<%= GV1.ClientID %>").rows;
for (i = 0; i < rows.length; i++) {
rows[i].cells[8].style.display = "none";
}
for (j = 0; j < rows.length; j++) {
rows[j].cells[9].style.display = "none";
}
if(someCondition)return true;
else return false;
}
更新:-您已将控件可见性设置为False,因此不会渲染控件。因此,您无法在javascript中获取Element,因为该控件将没有HTML。如果你想隐藏控件,只需使用Javascript:-
<asp:somecontrol id="ctrl" style="display:none" />
只需将隐藏列代码放入打印函数中,如下所示:
function PrintPage() {
rows = document.getElementById("<%= Gv1.ClientID %>").rows;
for (i = 0; i < rows.length; i++) {
rows[i].cells[8].style.display = "none";
rows[i].cells[9].style.display = "none";
}
var printContent = document.getElementById('<%= pnlDtls.ClientID %>');
var printWindow = window.open("All Records", "Print Panel", 'left=50000,top=50000,width=0,height=0');
printWindow.document.write(printContent.innerHTML);
printWindow.document.close();
printWindow.focus();
printWindow.print();
}
