我有以下代码:
<span style="margin:0px 2px 0px 2px;">
<asp:Label ID="labelPromptText" runat="server" Text="Selected Location:" />
<span id="spanSelectedLocation" style="padding:2px 2px 2px 2px; cursor:pointer;" onmouseover="javascript:SetBackgroundColor('spanSelectedLocation', '#E0E0E0');" onmouseout="javascript:SetBackgroundColor('spanSelectedLocation', '#FFFFFF');" onclick="ControlLocationsVisibility();">
<asp:Label ID="labelDisplay" runat="server" Text="None" Font-Bold="True" />
<img alt="Click to change" src="Images/downArrow.png" />
</span>
</span>
<asp:Panel ID="panelLocations" runat="server" DefaultButton="buttonFindLocation" style="position:absolute;border:solid 1px #E0E0E0;padding:10px 5px 5px 10px;background-color:#F7F7F7;width:350px;display:none;" >
Search: <asp:TextBox ID="textboxLocationSearch" runat="server" />
<asp:Button ID="buttonFindLocation" runat="server" Text="Find" OnClick="buttonFindLocation_Click" />
<input type="button" value="Cancel" onclick="javascript:ControlLocationsVisibility();"
<hr />
<asp:TreeView ID="TreeViewLocations" runat="server" OnSelectedNodeChanged="TreeViewLocations_SelectedNodeChanged" NodeIndent="10"></asp:TreeView>
</asp:Panel>
我希望能够在有人点击面板时隐藏panelLocations。我尝试了一个panelLocations的onblur事件,但是当点击TreeView时它总是消失。
当有人点击面板但不在面板内部时,如何隐藏面板?

如果你使用setTimeout()和clearTimeout()你可以像你提到的那样使用blurevent,但是当面板内的任何东西获得焦点时清除超时。这样,事件执行的唯一时间就是它“真的”失去了焦点。

另一种选择是处理身体上的onclick事件,但这可能会很快变慢。如果你要走那条路,它会看起来像这样:
<html>
<head>
<title>Hide Test</title>
</head>
<body>
<div id="first">
<p>This is the first div.</p>
</div>
<div id="second">
<p>This is the second div.</p>
</div>
<script type="text/javascript">
var first = document.getElementById("first");
var second = document.getElementById("second");
var isChildOf = function (ele, parent) {
if (ele.parentNode === null) {
return false;
} else if (ele.parentNode === parent) {
return true;
} else {
return isChildOf(ele.parentNode, parent);
}
};
document.body.onclick = function(e) {
if (isChildOf(e.target, second)) {
console.log("Hiding second.");
second.style.display = 'none';
} else {
console.log("Showing second.");
second.style.display = 'block';
}
};
</script>
</body>
</html>
