javascript - Backbone-forms.js - 如何在 github "docs"示例中呈现提交按钮

Question

这是 Backbone 形式的代码。现在，我想呈现一个提交按钮来验证我的文本字段和东西，这是记录在案的，除了如何将该提交按钮放入dom中。随意投反对票，无论如何，在我看来，这对于菜鸟来说很难理解

(function($) {
    var cities = {
        'UK': ['London', 'Manchester', 'Brighton', 'Bristol'],
        'USA': ['Washington DC', 'Los Angeles', 'Austin', 'New York']
    };

    //The form
    var form1 = new Backbone.Form({
        schema: {
            country: { type: 'Select', options: ['UK', 'USA'] },
            city: { type: 'Select', options: cities.UK },
            message: { type: 'Text'}
        }
    }).render();

    form1.on('country:change', function(form1, countryEditor) {
        var country = countryEditor.getValue(),
            newOptions = cities[country];
            form1.fields.city.editor.setOptions(newOptions);

    });

    //Add it to the page
    $('body').append(form1.el);
})(jQuery);

我的 friend ，你需要使用 BBF 模板!

虽然附加它是一种实现方式，但您应该真正坚持 BBF 实现按钮的方式。您可以创建不同的模板或在必要时重新使用它们，您可以从这里向表单添加属性等。希望这有助于...

检查工作演示: http://jsfiddle.net/c5QHr/116/

$(function() {

//// Set the template -----------------------------> 
Backbone.Form.setTemplates({
    customTemplate: '<form id="your-form-id">{{fieldsets}}<input id="your-form-cancel" type="reset" value="cancel" name="reset" /><input type="submit" value="submit" name="submit" />'

});

var cities = {
    'UK': ['London', 'Manchester', 'Brighton', 'Bristol'],
    'USA': ['Washington DC', 'Los Angeles', 'Austin', 'New York']
};

//The form
var form = new Backbone.Form({
    //// Use the template ----------------------------->
    template: 'customTemplate',
    schema: {
        country: { type: 'Select', options: ['UK', 'USA'] },
        city: { type: 'Select', options: cities.UK }
    }
}).render();

form.on('country:change', function(form, countryEditor) {
    var country = countryEditor.getValue(),
        newOptions = cities[country];

    form.fields.city.editor.setOptions(newOptions);
});

//Add it to the page
$('body').append(form.el);

////Do something with the buttons ----------------------------->

$("#your-form-id").submit(function(){alert('BBF Form was submitted!'); return false;});
$("#your-form-cancel").on('click',function(){alert('BBF Form was cancelled!'); });

});
