Bootstrap对话框确认onclick确认事件 [英] Bootstrap dialog confirmation onclick confirmation event

问题描述

我正在尝试编写自己的方法来调用BootstrapDialog并创建一个确认弹出窗口。如果用户选择确认，则该方法将返回true并继续调用jsf操作。我到目前为止的代码：

I am trying to write my own method that calls the BootstrapDialog and creates a confirmation popup. If the user selects "confirm" then the method will return true and continue to call the jsf action. The code I have so far:

 /**
 * Confirm window
 *
 * @param {type} message
 * @param {type} callback
 * @returns {undefined}
 */
BootstrapDialog.confirmation = function(title, message) {

    var callback = function(result) {
        console.log(result);
        return result;
    };

    var b = new BootstrapDialog({
        title: title,
        message: message,
        closable: false,
        data: {
            'callback': callback
        },
        buttons: [{
                label: 'Cancel',
                action: function(dialog) {
                    typeof dialog.getData('callback') === 'function' && dialog.getData('callback')(false);
                    dialog.close();
                }
            }, {
                label: 'Continue',
                cssClass: 'btn-primary',
                action: function(dialog) {
                    typeof dialog.getData('callback') === 'function' && dialog.getData('callback')(true);
                    dialog.close();
                }
            }]
    }).open();


    return callback;


};

我这样称呼js：

<h:commandButton type="button" value="Exit" action="myaction" styleClass="btn btn-default" onclick="return BootstrapDialog.confirmation('Data unsaved', 'Are you sure you want to continue');"/>

对话框弹出正常，问题是它没有返回true / false。我在这个例子之后模拟了我的js： http://nakupanda.github.io/bootstrap3-dialog/

The dialog pops up just fine, the issue is that it is not returning true / false. I have modeled my js after this example: http://nakupanda.github.io/bootstrap3-dialog/

推荐答案

我认为你真的不想扩展 BootstrapDialog 。而且我不希望对话框返回任何内容，因为它将异步操作（它必须等待用户按下按钮才能动作。）所以你需要通过它的回调来与它进行交互。

I don't think you really want to extend BootstrapDialog. And I wouldn't be expecting the dialog to return anything, since it's going to be operating asynchronously (it has to wait for the user to act by pressing a button.) So you need to interact with it through its callbacks.

我不熟悉 bootstrap3-dialog 超出我刚看到的浏览Github页面所以它可能会为你提供额外的回调或事件更整齐地做到这一点。但我认为这将大致完成你所追求的目标：

I'm not familiar with bootstrap3-dialog beyond what I just saw skimming its Github page so it may offer you additional callbacks or events to do this more neatly. But I think this will accomplish roughly what you're after:

function letUserExit() {
    // Add code here to redirect user where she expects to go 
    // when pressing exit button or to submit a form or whatever.
}

var exitConfirmDialog = new BootstrapDialog({
    title: 'Data unsaved',
    message: 'Are you sure you want to continue?',
    closable: false,
    buttons: [
        {
            label: 'Cancel',
            action: function(dialog) {
                dialog.close();
            }
        },
        {
            label: 'Continue',
            cssClass: 'btn-primary',
            action: function(dialog) {
                letUserExit();
            }
        }
    ]
});

// Add event to invoke dialog to your exit button here
$('button.exit').on('click', function() {
    // Show or open? Not quite sure what difference is. Use the one
    // that's most appropriate.
    exitConfirmDialog.show();

    // Stop any events (like a form being submitted or user being
    // redirected.) Need to wait until user responds to modal and
    // have event take place then.
    return false;
});
