我想添加功能来选择标题复选框中存在的所有项目，是否以及如何？

解决方案

< pre lang =cs> FOR 选择所有 复选框.. 此函数应在标题复选框上调用。

函数SelectAllCheckboxes1（chk）{
debugger;

（' ＃<％= WebDocumentGrid.ClientID％>'）。find（ input：checkbox）。each（function（）{
if （ this ！= chk）{
this 。 checked = chk。已检查;
}
}）;

}

此函数应在脚本标记中简单地调用并为其分配checkall复选框和其他子复选框id。

（ 。dummycb）。change（ function（）{
debugger;
var all =

I want to add functionality to select all the items that exist in the header checkbox, whether to and how?

解决方案

FOR ""Select ALL"" checkbox.. this function should be called on header checkbox.

 function SelectAllCheckboxes1(chk) {
            debugger;

('#<%=WebDocumentGrid.ClientID%>').find("input:checkbox").each(function () { if (this != chk) { this.checked = chk.checked; } }); } This function should be called simply in script tag and assign it the checkall checkbox and other child checkbox id.

(".dummycb").change(function () { debugger; var all =
