Question

我使用此提示语句并希望将另一个变量传递给回调函数：

正常行为：

Ext.MessageBox.prompt('Name', 'New folder name:', this.callbackCreateFolder);

callbackCreateFolder: function(btn, text) {
         console.log( btn ); // value as expected
         console.log( text ); // value as expected
}

我想要的是什么：

Ext.MessageBox.prompt('Name', 'New folder name:', this.callbackCreateFolder(oRecord));
callbackCreateFolder: function(btn, text, oRecord) {
         console.log( btn ); // undefined
         console.log( text ); // undefined
         console.log( oRecord ); // value as expected
}

将其他参数传递给函数的最佳方法是什么？

Answer 1

Ext.require('*');

function foo(btn, text, s1, s2) {
    console.log(s1, s2);
}

Ext.onReady(function(){
    Ext.MessageBox.prompt('Name', 'New folder name:', Ext.Function.bind(foo, null, ['bar', 'baz'], 2));
});

将参数添加到MessageBox提示符
