在jQuery/JavaScript中如何在滿足特定條件時退出for循環

-1

問題是，一旦我在JSON對象中找到「date」，我的for循環不停地滴答滴答。我認爲這導致我每次進入條件的「其他」部分。在jQuery/JavaScript中如何在滿足特定條件時退出for循環

我對JavaScript/jQuery相當陌生。從控制檯

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

輸出我的JavaScript代碼

// 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"); 
     $('.informationtechnologydivisionmanagerWednesdaySchedule').html("No Schedule Set" + "<br>" + "No Schedule Set"); 
     $('.informationtechnologydivisionmanagerThursdaySchedule').html("No Schedule Set" + "<br>" + "No Schedule Set"); 
     $('.informationtechnologydivisionmanagerFridaySchedule').html("No Schedule Set" + "<br>" + "No Schedule Set"); 
    } 
}

[破]（https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/break）是，如果以通常的方式 –

（條件）休息; –

willl break讓我離開if循環或for循環？ –

用來走出一個循環的兩個主要關鍵字break和continue。
break完全停止循環，並在循環後跳到該行。
continue只是停止當前的迭代，並跳轉到循環的開始，繼續下一次迭代。

所以，你需要的是break
