//确认功能的javascript函数

$(".item_delete").click(function()

)};

不工作，请帮忙

Answer 1

在代码下面使用语法错误。你错过了函数的开头{。

$(".item_delete").click(function() {
    return confirm("Are you sure you want to delete ?");
});

Answer 2

你应该在像这样的变量

中有确认值

$('body').on('click', '.item_delete', function() {

   return confirm("Are you sure you want to delete ?"); // if you just want 
   // to return the confirm

   // or you can delete based on conditions as
   var statusDelete = confirm("Are you sure you want to delete ?");


  if(statusDelete  == "true"){
// call function to delete
   }
 if(statusDelete  == "false"){
// call function when cancel clicked
   }

};

使用Javascript和jQuery确认删除
