Backbone-forms.js - 如何在github"docs"中呈现示例中的提交按钮

Question

这是骨干表格的代码.现在,我想呈现一个提交按钮来验证我的文本字段和内容,这是记录的,除了如何将提交按钮放入dom.随便投降,无论如何,在我看来这很难找到新手

(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);

你需要使用我的朋友BBF模板!

虽然附加它是一种方法,但你应该坚持BBF实现按钮的方式.您可以创建不同的模板或在必要时重复使用它们,从这里您可以向表单添加属性等.希望这可以帮助...

查看工作演示: 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!'); });

});
