ASP.NETを使用していますが、onclickとonserverclickの両方を持つリンクがあります。どちらも重要ですが、可能な限りonserverclickが実行されないようにonclickが必要です。
これが私が今遊んでいるアイテムです：
<ul class="clickables">
<asp:Repeater ID="MenuRepeater" runat="server">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<li class=" <%# ((DataRowView)Container.DataItem)["CSSClass"]%>"
style="background-color: <%# ((DataRowView)Container.DataItem)["BackgroundColour"]%>">
<a id="A1"
runat="server"
onserverclick="LinkClick"
onclick=<%# "return javascript:LinkClick('" + ((DataRowView)Container.DataItem)["Postback"] + "')" %>
customid='<%# ((DataRowView)Container.DataItem)["UniqueID"]%>'
href='<%# ((DataRowView)Container.DataItem)["PageFile"]%>'>
</a>
<%# ((DataRowView)Container.DataItem)["DisplayName"]%>
</li>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:Repeater>
</ul>
これが私がポストバックを止めることを期待しているJSです：
function LinkClick(parameters) {
if (parameters[0] == "False") {
return false;
}
私は何かが足りないのですか？これも可能ですか？onclickでfalseを返すことで通常のポストバックを防ぐことができますが、onserverclickを停止できますか？
更新 もう少しデバッグした後（しばらくwebdevから離れていました...）、JS関数が起動していません...

私がするときでさえ：
onclick='return LinkClick(False)'
また
onclick="return LinkClick(False)"
私はまだ得ます：
onclick="return LinkClick('True')"

したがって、メソッドを終了してtrue / falseを返すだけで、ポストバックを停止する必要がありますか？これは機能しません（よりレンダリングされたソース）。
