[英]OnClick is not working when i do OnClientClick=“function(); return false”
i have 5 asp:buttons that i want to change css class on when i click them so they are "marked". 我有5个asp:button,当我单击它们时要更改css类,因此它们被“标记”了。 I do this with javascript and it works fine. 我使用javascript执行此操作,效果很好。 But i also want to store a variable in code behind with the onClick. 但我也想在onClick后面的代码中存储一个变量。
My problem is, when i click my asp:button it refresh the page. 我的问题是,当我单击asp:button时,它将刷新页面。 I solved this with ;return false after my OnClientClick. 我在OnClientClick之后用; return false来解决了这个问题。 BUT when i have return false, the buttons OnClick doesnt fire. 但是当我返回false时,OnClick按钮不会触发。 So i need help with getting these both things to work at same time: 因此,我需要帮助使这两种功能同时起作用:
html html
<asp:Button ID="Button1" runat="server" Text="1" OnClick="button1_Click" OnClientClick="change_select(this); return false;" CssClass="button black"/>
javascript javascript
function change_select(objs) {
$('.darkgray').removeClass('darkgray').addClass('black');
objs.className = "button darkgray";
} }
code behind 背后的代码
int[] answerArray = new int[28];
int answer = 0;
int currentQ = 0;
protected void button1_Click(object sender, EventArgs e)
{
answer = 1;
}
protected void buttonNext_Click(object sender, EventArgs e)
{
answerArray[currentQ] = answer;
currentQ++;
}
You cannot prevent to refresh the page if you have intention to store a value in the code behind using ASP.NET Webforms. 如果您打算使用ASP.NET Webforms在后面的代码中存储值,则不能阻止刷新页面。 See this related SO question How to stop to reload page when click the button? 看到这个相关的SO问题如何在单击按钮时停止重新加载页面?
