htmlコードは
<script type="text/jscript">
function ajaxcall() {
$.ajax({
type: "POST",
url: "index.aspx/lvimgclick",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ value: "test" }),
dataType: "json",
});
};
</script>
<img src='images/img1.jpg' onclick='return ajaxcall();' /> // calling script
<asp:LinkButton ID="lvlink1" OnClick="lvimg1_Click" CssClass="lv-under" runat="server" >
<asp:Image ID="lvimg1" runat="server" ImageUrl="~/images/spacer.gif" />
<asp:LinkButton ID="lvlink2" OnClick="lvimg2_Click" CssClass="lv-under" runat="server" >
<asp:Image ID="lvimg2" runat="server" ImageUrl="~/images/spacer.gif" />
<asp:LinkButton ID="lvlink3" OnClick="lvimg3_Click" CssClass="lv-under" runat="server" >
<asp:Image ID="lvimg3" runat="server" ImageUrl="~/images/spacer.gif" />
<asp:LinkButton ID="lvlink4" OnClick="lvimg4_Click" CssClass="lv-under" runat="server" >
<asp:Image ID="lvimg4" runat="server" ImageUrl="~/images/spacer.gif" />
.cs コード
[WebMethod]
public static string lvimgclick()
{
return "hi";
}
protected void lvimg1_Click(object sender, EventArgs e)
{
lvlink1.CssClass = "lv-under";
lvimg1.ImageUrl = "~/images/1.jpg";
lvlink2.CssClass = "lv-under";
lvimg2.ImageUrl = "~/images/spacer.gif";
lvlink3.CssClass = "lv-under";
lvimg3.ImageUrl = "~/images/spacer.gif";
lvlink4.CssClass = "lv-under";
lvimg4.ImageUrl = "~/images/spacer.gif";
}
欲しいものは:
[WebMethod]
public static string lvimgclick()
{
lvimg1_Click(null, null);
return "hi";
}
また
[WebMethod]
public static string lvimgclick()
{
lvlink1.CssClass = "lv-under";
lvimg1.ImageUrl = "~/images/1.jpg";
lvlink2.CssClass = "lv-under";
lvimg2.ImageUrl = "~/images/spacer.gif";
lvlink3.CssClass = "lv-under";
lvimg3.ImageUrl = "~/images/spacer.gif";
lvlink4.CssClass = "lv-under";
lvimg4.ImageUrl = "~/images/spacer.gif";
return "hi";
}
何をしなければなりませんか?lvimg1_Click(null, null);も使用する必要があります。およびlvlink1.CssClass = "lv-under1"; Webメソッドではない多くの機能で
