封装ajax方法

function ajaxRequest(type, url, data, callback, loading, cache) {
var ajaxConfig = {
url: '',
data: {},
callback: null,
loading: true,
cache: true,
async: true
};
// 判断每一个参数url的类型
// 如果是对象则是请求参数对象
// 如果是字符串则是请求URL,参数和回调要继续检测后面的参数
if (typeof url === 'string') {
ajaxConfig.url = url;
ajaxConfig.data = data;
ajaxConfig.callback = callback;
ajaxConfig.loading = typeof(loading) === 'undefined' ? true : loading;
ajaxConfig.cache = cache;
} else {
ajaxConfig = $.extend({}, ajaxConfig, url);
}
$.ajax({
type: type,
url: ajaxConfig.url,
data: ajaxConfig.data,
beforeSend: function() {
if (ajaxConfig.loading) { $.showLoading(); }
},
dataType: 'json',
cache: ajaxConfig.cache,
async: ajaxConfig.async,
success: function(re) {
if (ajaxConfig.loading) { $.hideLoading() };
if (re.result == ) {
if (re.msg != '') {
$.toast(re.msg, function() {
if (re.redirect) {
window.location.href = re.redirect;
} else {
ajaxConfig.callback(re.data);
}
});
} else {
ajaxConfig.callback(re.data);
}
} else {
$.toast(re.msg, 'forbidden');
}
},
error: function(re) {
ajaxConfig.loading && $.hideLoading();
$.toast("Error", "forbidden");
console.error(re.responseText);
}
})
}
function ajaxGet(url, data, callback, loading) {
ajaxRequest('get', url, data, callback, loading, true);
}
function ajaxPost(url, data, callback, loading) {
ajaxRequest('post', url, data, callback, loading, false);
}
