我的GridView中有很多模板字段。其中我有一个名为“chkSelect”的CheckBox,在另一个模板字段中我有一个名为“lnkgvQCAttribute”的LinkButton。这里我想在CheckBox未选中时禁用LinkButton,并在选中CheckBox时启用LinkButton。如何使用JavaScript执行此操作?
这是我的GridView的列:
<Columns>
<asp:TemplateField HeaderText="S.No.">

我需要你的所有建议......

首先添加对jQuery的引用(下载并将其放在一个站点文件夹中,例如 Scripts ):
<script src="Scripts/jquery-1.2.6.pack.js" type="text/javascript"></script>
然后你应该为你的元素创建一个 CssClass 名称,如:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server" Checked='<%#Bind("Select") %>' CssClass="chkSelect" />
</ItemTemplate>
<HeaderTemplate>
<asp:CheckBox ID="chkSelectAll" runat="server" onclick="CheckAll();" />
</HeaderTemplate>
<ControlStyle Width="20px" />
<ItemStyle Width="20px" />
</asp:TemplateField>
和
<asp:TemplateField HeaderText="QC">
<ItemTemplate>
<asp:LinkButton ID="lnkgvQCAttribute" runat="server" CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>'
CommandName="QC" Text="QC" CssClass="lnkgvQCAttribute" />
</ItemTemplate>
</asp:TemplateField>
现在,您可以使用JS找到您的元素并控制它们的行为。在这种情况下,复选框位于span
,然后是td
,最后是tr
。您应导航至tr
,在tr
中找到包含lnkgvQCAttribute
类的元素,并对其进行控制:
<script type="text/javascript">
$(document).ready(function () {
$("span.chkSelect input").click(function () {
var enabled = this.checked;
var link = $(this).parent().parent().parent().find("a.lnkgvQCAttribute");
if (enabled) {
var href = $(link).attr("data-href");
$(link).attr("href", href);
$(link).removeAttr("data-href");
} else {
var href = $(link).attr("href");
$(link).attr("data-href", href);
$(link).removeAttr("href");
}
});
});
</script>
享受!

在复选框
上拨打onclick="disableLinkButton(this)"
function disableLinkButton(obj) {
var rowObject = getParentRow(obj);
if(obj.checked) {
rowObject.childNodes[3].disabled = true // debug and check, row Object will contain that link button as its childnodes
}
else {
rowObject.childNodes[3].disabled = false;
}
}
function getParentRow(obj) {
obj = obj.parentElement;
while(obj.tagName != "TR")
return obj;
}

在页面上添加以下javascript和样式:
<script type="text/javascript">
$(function () {
$("input[id*='chkSelect_']", "#<%= GridView1.ClientID %>")
.click(function () {
var linkButton = $(this).closest("tr").find("a[id*='lnkgvQCAttribute_']");
if (this.checked) {
EnableLinkButton(linkButton);
}
else {
DisableLinkButton(linkButton);
}
}) //disable turned off linkbuttons on page load
.not(":checked").each(function () {
DisableLinkButton($(this).closest("tr").find("a[id*='lnkgvQCAttribute_']"));
});
});
function EnableLinkButton(lb) {
$(lb)
.removeClass("disabled")
.attr("href", function () {
return !$(this).is("[href^='javascript:__doPostBack']") ? this.href.replace('retun false;', '__doPostBack') : this.href;
});
}
function DisableLinkButton(lb) {
$(lb)
.addClass("disabled")
.attr("href", function () { return $(this).is("[href^='javascript:__doPostBack']") ? this.href.replace('__doPostBack', 'retun false;') : this.href; });
}
</script>
<style type="text/css">
a.disabled
{
color: #e3e3e3;
text-decoration: none;
cursor: default;
}
</style>
