我想使用Bootstrap Modal按钮在click事件中返回结果

Question

My aim is to override the jquery confirm() function with `function

confirm(message){
        //There is a modal opened already
        $('#confirm').modal('show', {backdrop: 'static'}); //Show second modal on top of the first modal
        $('#confirm').find('.modal-title').html(message);
                $('.confirm').on('click',function(){ //on Confirm button click of the second modal
                        $('#confirm').removeClass('fade').modal('hide');//Hide the Second modal
                        $('.page-body').addClass('modal-open'); // Addig back modal-open class to body element to prevent modal conflict
                        callback(); //some suggested this but it doesnt work
                        return true; //I want to return this to the function called this function but i get no results
                });
                $('.cancel').on('click',function(){
                        $('#confirm').removeClass('fade').modal('hide');
                        $('.page-body').addClass('modal-open'); 
                        callback(); 
                        return false; 
                });

            $('.close').on('click',function(){
                    $('#confirm').removeClass('fade').modal('hide');
                    $('.page-body').addClass('modal-open'); 
                    callback(); 
                    return 'cancel';
            });
}`  I am not getting any results when I call the function

1. jQuery doesn't have a confirm() function, so you're either using the browser's built-in function or some plugin...

2. You're not returning anything from your custom confirm function. You're defining event handlers that may eventually return values, but they won't return anything until they're called.

It's hard to figure out what this function should be doing. Can you summarize the logic in English?

Here's what it looks like your code is doing right now:

When the user calls the built-in confirm function,

1. Show a modal dialog

2. Set its title to the message parameter

3. Do nothing right now, but attach an onclick event handler to the confirm class.

4. Do nothing right now, but attach an onclick event handler to the cancel class.

5. Do nothing right now, but attach an onclick event handler to the close class.

It's too late to do anything useful with those event handlers at that point, and you'll never see their return values.

If you post your HTML and say step-by-step, in detail what order you want events to happen in, people can help. But otherwise I'm not sure how.
