问题描述
How to set Slider control Value from ASP.NET AJAX Control Toolkit with JavaScript function? Is this even possible?
解决方案
Sure is! You have to set the value of asp:TextBox control that's associated with your SliderExtender to the value that you want. So for this ASP markup:
<asp:TextBox ID="sliderBox" runat="server" ClientIDMode="Static"></asp:TextBox>
<asp:SliderExtender ID="sliderBox_SliderExtender" runat="server" Enabled="True"
Maximum="100" Minimum="0" TargetControlID="sliderBox">
</asp:SliderExtender>
<asp:Button ID="incButton" runat="server" Text="incrementSlider"
onclientclick="change();" />
Which is basically:
- an
asp:TextBoxnamed sliderBox (for theSliderExtenderto use) - an
asp:SliderExtendersliderBox_SliderExtender (with basically default values) - an
asp:Buttonnamed incButton. This has anonClientClickproperty that calls thechange()javascript function
And here is the change() function:
<script type="text/javascript">
function change() {
document.getElementById("sliderBox").value += 10;
}
</script>
The change() function increments the value in the asp:TextBox control by 10, thus increasing the sliders position each time you click the button.
