Backbone.js的带参数的获取 [英] Backbone.js fetch with parameters

问题描述

继文档，我所做的：

var collection = new Backbone.Collection.extend({
        model: ItemModel,
        url: '/Items'
})

collection.fetch({ data: { page: 1} });

网址竟然是：的http：//本地主机：1273 /项目[对象％20Object]

我期待像的http：//本地主机：1273 /项目页= 1

那么，如何通过PARAMS在fetch方法？

So how do I pass params in the fetch method?

推荐答案

改变：

collection.fetch({ data: { page: 1} });

到

collection.fetch({ data: $.param({ page: 1}) });

因此​​，与出过这样做，这叫做有你的 {数据：{页：1}} 对象选项

Backbone.sync = function(method, model, options) {
    var type = methodMap[method];

    // Default JSON-request options.
    var params = _.extend({
      type:         type,
      dataType:     'json',
      processData:  false
    }, options);

    // Ensure that we have a URL.
    if (!params.url) {
      params.url = getUrl(model) || urlError();
    }

    // Ensure that we have the appropriate request data.
    if (!params.data && model && (method == 'create' || method == 'update')) {
      params.contentType = 'application/json';
      params.data = JSON.stringify(model.toJSON());
    }

    // For older servers, emulate JSON by encoding the request into an HTML-form.
    if (Backbone.emulateJSON) {
      params.contentType = 'application/x-www-form-urlencoded';
      params.processData = true;
      params.data        = params.data ? {model : params.data} : {};
    }

    // For older servers, emulate HTTP by mimicking the HTTP method with `_method`
    // And an `X-HTTP-Method-Override` header.
    if (Backbone.emulateHTTP) {
      if (type === 'PUT' || type === 'DELETE') {
        if (Backbone.emulateJSON) params.data._method = type;
        params.type = 'POST';
        params.beforeSend = function(xhr) {
          xhr.setRequestHeader('X-HTTP-Method-Override', type);
        };
      }
    }

    // Make the request.
    return $.ajax(params);
};

所以它发出的数据到 jQuery.ajax 将尽力追加任何 params.data 是URL。

So it sends the 'data' to jQuery.ajax which will do its best to append whatever params.data is to the URL.
