请问下在repeater中针对每行数据进行全选如何做?
具体就是在 <HeaderTemplate> 中放一个复选框进行全选/全不选操作, <ItemTemplate> 则有若干项复选框,受上面所控制.
我以前做过整个repeater的全选,但不知道这种一个repeater有多处分别全选是不是可以做?如果可以请给点思路或代码.如不行说一下一搬如何解决这种问题.多谢!
------解决方案--------------------function SetCheckBoxState()
{
var dom = document.all;
var el = event.srcElement;
if(el.tagName == "INPUT " && el.type.toLowerCase()== "checkbox ")
{
for(i=0;i <dom.length;i++)
{
if(dom[i].tagName== "INPUT " && dom[i].type.toLowerCase()== "checkbox ")
{
dom[i].checked = false;
}
}
}
el.checked = !el.checked;
}
<asp:TemplateColumn HeaderText= "选择 " HeaderStyle-HorizontalAlign= "Center ">
<HeaderStyle Font-Size= "10pt " Font-Bold= "True " Wrap= "False " HorizontalAlign= "Center " VerticalAlign= "Middle "> </HeaderStyle>
<ItemStyle Wrap= "False " HorizontalAlign= "Center "> </ItemStyle>
<ItemTemplate>
<asp:CheckBox id= "chkExport " Runat= "server " BackColor= "Transparent " Width= "35px " Height= "10px "> </asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
------解决方案--------------------可以在checkbox的id上做一些手脚,数据绑定的时候让相关的checkbox的id有关系,借用purplesunshine(紫色阳光)的代码稍改一下
