我有这个javascript代码:
<script>
$(document).ready(function() {
var progValue1 = 100;
var progValue2 = 30;
$("#progressbar").progressbar({ value: progValue1});
$("#progressbar2").progressbar({ value: progValue2 });
});
</script>
我想在点击按钮时从后面的代码中更改两个变量(progValue1
和progValue2
)的值.....
这是按钮的代码
<asp:Button ID="btnConfirm" CssClass="button" SkinID="Common" runat="server" Text= "Confirm" OnClick="btnConfirm_Click" />
如何从btnConfirm
方法的C#代码更改这些值?

添加两个属性,即
private int _progValue1 = 100;
private int _progValue2 = 30;
protected int ProgValue1 { get { return this._progValue1; }}
protected int ProgValue2 { get { return this._progValue2; }}
修改你的JS:
<script>
$(document).ready(function() {
var progValue1 = <%=ProgValue1%>;
var progValue2 = <%=ProgValue2%>;
$("#progressbar").progressbar({ value: progValue1});
$("#progressbar2").progressbar({ value: progValue2 });
});
</script>
然后在OnClick事件处理程序中设置值:
this._progValue1 = 40;
this._progValue2 = 20;

我从您的查询中假设您想要从代码隐藏更改Javascript变量的值意味着,您希望将代码后面的值发送到javascript。您可以使用ScriptManager.RegisterClientScriptBlock来实现此目的。为了更加高兴,请参阅以下代码:
JS
function ChangeValue(value1)
{
yourvariable = value1;
}
背后的代码
private void SomeMethod()
{
string newvalue = "test value"; //need to pass this to JS var
ScriptManager.RegisterClientScriptBlock(this,typeof(Page),"key","ChangeValue("+ newvalue +");",true);
}

$(function () {
var progValue1 = parseInt('<%=ProgValue1%>');
$("#progressbar").progressbar({ value: progValue1 });
});
private int _progValue1 = 1;
protected int ProgValue1
{
get
{
return _progValue1;
}
}
