我有以下错误消息可用HTML:
<div class="alert alert-error">
<div class="content">
<p>
<i class="fa fa-warning"></i>
User not found.
</p>
</div>
</div>
如何在Backbone中为没有失去良好做法的用户显示该内容?
我的意思是,让我的视图以可靠性呈现它的最佳方法是什么?
user.save({}, {
success: function(model, response) {
if (response.error) {
// hey, the message goes here!
}
}
});

您可以使用新方法扩展Backbone View以显示如下错误:
_.extend(Backbone.View.prototype, {
showError: function(message) {
// Here you render your error, may be like this : $('#errorInfo').html(message);
}
});
并在您看来:
var self = this; // I assume that you are in the view
user.save({}, {
success: function(model, response) {
if (response.error) {
self.showError(/* things you want to pass */);
}
}
});

对我来说,最佳做法是创建一个对象 errorMessageView
HTML:
<div id="errorInfo"></div>
JS:
var errorMessageView = Backbone.View.extend({
el: "#errorInfo",
initialize: function() {
},
renderInnerHTML: function(message) {
this.el.innerHTML = message;
}
});
var errorMessage = new errorMessageView ;
user.save({}, {
success: function(model, response) {
if (response.error) {
errorMessage.renderInnerHTML(response.error);
}
}
});
