Question

我将数据动态地附加到我的表格中：

    public void Configuration(IAppBuilder appBuilder)
    {
        var configuration = new HttpConfiguration();

        appBuilder.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
        appBuilder.UseWebApi(configuration);

        configuration.Routes.Add("API Default", new HttpRoute("{Controller}"));

        appBuilder.Run((owinContext) =>
        {
            owinContext.Response.ContentType = "text/plain";
            return owinContext.Response.WriteAsync("Api is available at:  /ReceiptPrinter");
        }); 
    }

我的表结构是：

function myFunctionEdit()
{

var table = document.getElementById("nomiTable");
var len = table.rows.length;
var row = table.insertRow(len);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
var cell6 = row.insertCell(5);

cell1.innerHTML = len;
cell2.innerHTML = name;
cell3.innerHTML = dob;
cell4.innerHTML = relation;
cell5.innerHTML = share;
cell6.innerHTML = "<a href = \"#\" data-toggle=\"modal\" data-target=\"#editNomiModal\" id = \"editNominHref\" name = \"editNominHref\" ><img border=\"0\" alt=\"Edit Nominee\" src=\"images/edit.png\" width=\"15\" height=\"15\"/></a>";

$('#editNomiModal').modal('hide');
return false;
}

#editNominHref上的JQuery函数点击：

<table id = "nomiTable" name = "nomiTable" class="table table-striped table-hover">
<thead>
<tr>
..
</tr>
</thead>
<tbody>
<tr>
..Dynamically generated columns...
<td>
<a href = "#" data-toggle="modal" data-target="#editNomiModal" id = "editNominHref" name = "editNominHref" >
<img border="0" alt="Edit Nominee" src="images/edit.png" width="15" height="15"/>
</a>
</td>
</tr>

问题： 该方法不适用于动态生成的$("#editNominHref").on('click', function(e) { alert($(this).closest('tr').index()); });。任何帮助都将受到高度赞赏。

将event delegation用于此目的。

- (IBAction)btnFacebookPressed:(id)sender {
    FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorBrowser;
    [login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
     {
         if (error)
         {
             // Process error
         }
         else if (result.isCancelled)
         {
             // Handle cancellations
         }
         else
         {
             if ([result.grantedPermissions containsObject:@"email"])
             {
                 NSLog(@"result is:%@",result);
                 [self fetchUserInfo];
                 [login logOut];
             }
         }
     }];
}

- (void)fetchUserInfo {
    if ([FBSDKAccessToken currentAccessToken])
    {
        NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);

        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location , friends ,hometown , friendlists"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error)
             {
                 NSLog(@"resultis:%@",result);

             }
             else
             {
                 NSLog(@"Error %@",error);
             }
         }];
    }
}
