Question

问题是，一旦我在JSON对象中找到“日期”，我的for循环就会一直在滴答作响。我认为这导致我每次都进入条件的“Else”部分。

我是JavaScript / jQuery的新手。

来自控制台的输出

report-generation.js:443 Entering Else Loop for 02/13/2017. The date from the JSON file is 02/6/2017
report-generation.js:434 Entering If Loop for 02/13/2017. The date from the JSON file is 02/13/2017
report-generation.js:443 Entering Else Loop for 02/13/2017. The date from the JSON file is 02/20/2017
report-generation.js:488 02/6/2017 date from JSON. Selected Date is 02/13/2017
report-generation.js:488 02/13/2017 date from JSON. Selected Date is 02/13/2017
report-generation.js:488 02/20/2017 date from JSON. Selected Date is 02/13/2017

我的JavaScript代码

// Get Information Technology Division Manager Schedule
for (var i = 0; i < informationtechnologydivisionmanager.length; i++)
{
    var emailAddressParts = informationtechnologydivisionmanager[i].name.split(' ');
    var emailAddress = emailAddressParts[0] + "." + emailAddressParts[1] + "@example.com";
    var createLink = "mailto:" + emailAddress + "?subject=Schedule for " + dateFromInput + "&body=This is a template. Please remove these lines and add your own";

    if (informationtechnologydivisionmanager[i].date == theSelectedDate)
    {
        console.log("Entering If Loop for " + theSelectedDate + ". The date from the JSON file is " + informationtechnologydivisionmanager[i].date);
        $('.informationtechnologydivisionmanagerName').html("<a href='" + createLink + "'>" + informationtechnologydivisionmanager[i].name + "</a><br>");
        $('.informationtechnologydivisionmanagerTitle').html(informationtechnologydivisionmanager[i].title);
        $('.informationtechnologydivisionmanagerMondaySchedule').html(informationtechnologydivisionmanager[i].mondayAM + "<br>" + informationtechnologydivisionmanager[i].mondayPM);
        $('.informationtechnologydivisionmanagerTuesdaySchedule').html(informationtechnologydivisionmanager[i].tuesdayAM + "<br>" + informationtechnologydivisionmanager[i].tuesdayPM);
        $('.informationtechnologydivisionmanagerWednesdaySchedule').html(informationtechnologydivisionmanager[i].wednesdayAM + "<br>" + informationtechnologydivisionmanager[i].wednesdayPM);
        $('.informationtechnologydivisionmanagerThursdaySchedule').html(informationtechnologydivisionmanager[i].thursdayAM + "<br>" + informationtechnologydivisionmanager[i].thursdayPM);
        $('.informationtechnologydivisionmanagerFridaySchedule').html(informationtechnologydivisionmanager[i].fridayAM + "<br>" + informationtechnologydivisionmanager[i].fridayPM);
    } else {
        console.log("Entering Else Loop for " + theSelectedDate + ". The date from the JSON file is " + informationtechnologydivisionmanager[i].date);
        $('.informationtechnologydivisionmanagerName').html("<a href='" + createLink + "'>" + informationtechnologydivisionmanager[i].name + "</a><br>");
        $('.informationtechnologydivisionmanagerTitle').html(informationtechnologydivisionmanager[i].title);
        $('.informationtechnologydivisionmanagerMondaySchedule').html("No Schedule Set" + "<br>" + "No Schedule Set");
        $('.informationtechnologydivisionmanagerTuesdaySchedule').html("No Schedule Set" + "<br>" + "No Schedule Set");

Answer 1

用于退出循环的两个主要关键字是break和continue break完全停止循环并在循环后跳转到该行 continue只是停止当前迭代，然后跳转到循环的开头，继续下一次迭代。

所以你需要的是break
