Here is and a screenshot I uploaded for you根据您在评论中的建议,我编辑了我的帖子,发布了我的代码的更新版本。我附上了/ ** /我的原始帖子以帮助您。我无法在关闭对话框中关闭对话框
/*In jointJS I try using a `ui.dialog` to delete all my graph with the following code:
var dialog = new joint.ui.Dialog({
width: 400,
title: 'Create new process',
content: '<b>Cleanup current drawing?</b>',
closeButton: false,
buttons: [
{ action: 'ok', content: 'OK' },
{ action: 'cancel', content: 'CANCEL' }
]
});
dialog.on('action:ok', this.graph.clear, this.graph);
dialog.on('action:cancel', dialog.close, dialog);
dialog.open();
},
After pressing OK button I successfully delete my graph but my dialog still remains without being able to delete it.
Any help please? */
这是我更新的代码,不幸的是仍然无法按预期工作。我提醒你,其中显示一个确定此对话框的形式和取消按钮,我想下面的:
1)当按下OK我想: 一)删除我目前的图形和 B)关闭我的对话框
2)当按下取消我想: 闭上对话框(这在我的最初版本与dialog.close
successfylly工作)
openNew: function() {
// By pressing Create New Process button, a popup form asks for
//our confirmation before deleting current graph
var dialog = new joint.ui.Dialog({
width: 400,
title: 'Create new process',
content: '<b>Cleanup current drawing?</b>',
closeButton: false,
buttons: [
{ action: 'ok', content: 'OK' },
{ action: 'cancel', content: 'CANCEL' }
]
});
//Since in 'action:ok' of dialog.on the 3rd parameter is used in the
//callback of multi_hand we must pass dialog and graph both together.To do so
//we enclose them in an object named together and we pass it instead
together= {dialog : dialog, graph : this.graph};
//Since jointJS supports assigning multiple events for same handler
//BUT NOT multiple handlers for the same event we create function multi_hand
multi_hand: function (together)
{
together.graph.clear();
together.dialog.close();
}
dialog.on('action:ok', multi_hand, together);
dialog.on('action:cancel', dialog.close, dialog);
dialog.open();
},
通过使用这种新的代码我joinjtJS项目意外崩溃。 我会如何让OK按钮起作用?
我更新了我的帖子,请检查它。 –
在'openNew'函数体中的某处尝试'console.log(this.graph)'。它不应该是'未定义' –
我以这种方式解决了我的问题,我只是想与大家分享它作为参考。 –
