我的母版页位于 runat="server" 这样的表单中:
<body>
<form id="Form1" runat="server">
<asp:ContentPlaceHolder ID="MainContent" runat="server"/>
</form>
</body>
在我的一个页面中,我添加了一个文本区域、一个按钮(html 控件,而不是 ASP)和一些类似这样的 javascript 代码:
<textarea id="ContentTextArea" class="ContentTextArea" rows="2" cols="20"></textarea>
<button id="ClearButton" class="Button2" onclick="ClearButtonClick();">CLEAR</button>
<script type="text/javascript">
function ClearButtonClick() {
document.getElementById("ContentTextArea").value = "";
}
</script>
我希望javascript代码(正在清除textarea文本)在客户端单击“清除”按钮而不向服务器发送请求时运行,但是因为我<form id="Form1" runat="server">
在母版页中有按钮将数据提交到服务器和页面被重新加载。
我的母版页中必须有<form id="Form1" runat="server">
,但我也想在我的代码中使用 JavaSctipt,它将在客户端运行。
谢谢
