寫了個函數(shù)，輸入三個參數(shù)，前兩個參數(shù)傳給url， 通過get請求，獲取發(fā)票信息對象，第三個參數(shù)判斷要獲取的信息，從然后返回對應(yīng)的值。

同事點撥，這樣寫效率低，直接返回對象，用的時候現(xiàn)取，不需要在函數(shù)中返回值。果然溝通使人進步。 改進后的代碼：

function getInvocieInfo(user_id, taskid) {
    var invoiceObj = {};
    $.ajax({
        type: 'GET',
        dataType: 'json',
        url: 'http://180ly66419.iok.la:5000/api/detect_in?1=1&user_id=' + user_id + '&task_id=' + taskid,
        async: false,
        timeout: 5,
        data: {
            q: "select * from json where url=\"http://www.w3dev.cn/json.asp\"",
            format: "json"
        },
        success: function (response) {
            responseData = JSON.stringify(response);
            invoiceObj = eval('(' + responseData + ')');
        },
        error: function () {
            alert('服務(wù)器異常，獲取發(fā)票信息失??！');
        }
    });
    return invoiceObj
}

使用的時候調(diào)用：

var inoviceObj = getInvocieInfo(user_id, taskList[i]);
invoiceInfo["invoiceTextID"]  = inoviceObj.data["invoice_code"];
invoiceInfo["invoiceTextNum"]  = inoviceObj.data["invoice_num"];

修改前

function getInvocieInfo(user_id, taskid, textInvocetype) {
    $.ajax({
        type: 'GET',
        dataType: 'json',
        url: 'http://180ly66419.iok.la:5000/api/detect_in?1=1&user_id=' + user_id + '&task_id=' + taskid,
        async: false,
        timeout: 5,
        data: {
            q: "select * from json where url=\"http://www.w3dev.cn/json.asp\"",
            format: "json"
        },
        success: function (response) {
            responseData = JSON.stringify(response);
            var invoiceObj = eval('(' + responseData + ')');
            invoiceID = invoiceObj.data['invoice_code'];
            invoiceNo = invoiceObj.data['invoice_num'];
        },
        error: function () {
            alert('服務(wù)器異常，獲取發(fā)票信息失敗！');
        }
    });
    if (textInvocetype == "textInvoiceNum") {
        return invoiceNo;
    }
    else if (textInvocetype == "textInvoiceID") {
        return invoiceID;
    }
}
