问题描述

不知道是什么原因发生这种情况，但在点击一个按钮，我称之为一个jQuery的Ajax控制，之后我就不想继续提交表单，但在此之前的页面仍然被提交。

 ＆LT; ASP：ImageButton的ID =btnContinue的OnClick =btnContinue_Click=服务器的OnClientClick =返回false; /＆GT;

和jQuery的：

  $（＃＆LT;％= btnContinue.ClientID％＆gt;中）。点击（函数（）{
            VAR currentpickupLocation =的document.getElementById（＆LT;％= ddlPickupLocation.ClientID％＆gt;中）值。
            VAR currentpickupDate =的document.getElementById（＆LT;％= txtPickupDate.ClientID％＆gt;中）。值;
            变种的CurrentCulture =＆其中;％= GetCulture（）％＆gt;中;
            变种PARAMS = $ .toJSON（{pickupLocation：currentpickupLocation，pickupDate：currentpickupDate}）;
            $阿贾克斯（{
                键入：POST，
                网址：LocationService.asmx / GetBlackoutDates
                数据：参数，可以
                的contentType：应用/ JSON的;字符集= UTF-8，
                数据类型：JSON，
                成功：函数（位置）{
                    返回false;
                }
            }）;
        }）;

解决方案

您需要有一个回虚假的点击区域，像这样：

  $（＃＆LT;％= btnContinue.ClientID％＆gt;中）。点击（函数（）{
    VAR currentpickupLocation =的document.getElementById（＆LT;％= ddlPickupLocation.ClientID％＆gt;中）值。
    VAR currentpickupDate =的document.getElementById（＆LT;％= txtPickupDate.ClientID％＆gt;中）。值;
    变种的CurrentCulture =＆其中;％= GetCulture（）％＆gt;中;
    VAR PARAMS = $ .toJSON（{
        pickupLocation：currentpickupLocation，
        pickupDate：currentpickupDate
    }）;
    $阿贾克斯（{
        键入：POST，
        网址：LocationService.asmx / GetBlackoutDates
        数据：参数，可以
        的contentType：应用/ JSON的;字符集= UTF-8，
        数据类型：JSON，
        成功：函数（位置）{
            返回false;
        }
    }）;
    返回false; //这告诉浏览器不提交
}）;

Not exactly sure why this is happening, but upon click of a button I call a JQuery Ajax control, after that I do not want to continue submitting the form, but before the page gets still submitted.

<asp:ImageButton id="btnContinue" OnClick="btnContinue_Click" runat="server" OnClientClick="return false;" />

and the jQuery:

            $("#<%=btnContinue.ClientID%>").click(function() {
            var currentpickupLocation = document.getElementById("<%=ddlPickupLocation.ClientID %>").value;
            var currentpickupDate = document.getElementById("<%=txtPickupDate.ClientID %>").value;
            var currentCulture = "<%= GetCulture() %>";
            var params = $.toJSON({pickupLocation: currentpickupLocation, pickupDate: currentpickupDate});
            $.ajax({
                type: "POST",
                url: "LocationService.asmx/GetBlackoutDates",
                data: params,
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function(locations) {
                    return false;
                }
            });
        });

解决方案

You need to have a return false in the click area like so:

$("#<%=btnContinue.ClientID%>").click(function() {
    var currentpickupLocation = document.getElementById("<%=ddlPickupLocation.ClientID %>").value;
    var currentpickupDate = document.getElementById("<%=txtPickupDate.ClientID %>").value;
    var currentCulture = "<%= GetCulture() %>";
    var params = $.toJSON({
        pickupLocation: currentpickupLocation,
        pickupDate    : currentpickupDate
    });
    $.ajax({
        type: "POST",
        url: "LocationService.asmx/GetBlackoutDates",
        data: params,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(locations) {
            return false;
        }
    });
    return false;  //this tells the browser not to submit
});
