使用for循环压缩代码 [英] Using a for loop to condense code

问题描述

我有以下代码，我想将这些代码浓缩为for循环，但不确定如何执行.我尝试查看其他帖子，但被卡住了.

I have the following code which I would like to condense into a for loop but not sure how. I tried looking at other posts but got stuck.

总共有15个数字，所以类似(i = 1; i< = 15; i ++)

There are 15 numbers all together so something like for (i = 1; i <= 15; i++)

       if(checksquare1save=="true"){
            $("#checksquare1").toggleClass("checksquareON");
        }

        else{
            $("#checksquare1").removeClass("checksquareON");
        }

        if(checksquare2save=="true"){
            $("#checksquare2").toggleClass("checksquareON");
        }

        else{
            $("#checksquare2").removeClass("checksquareON");
        }

        if(checksquare3save=="true"){
            $("#checksquare3").toggleClass("checksquareON");
        }

        else{
            $("#checksquare3").removeClass("checksquareON");
        }

        if(checksquare4save=="true"){
            $("#checksquare4").toggleClass("checksquareON");
        }

        else{
            $("#checksquare4").removeClass("checksquareON");
        }

        if(checksquare5save=="true"){
            $("#checksquare5").toggleClass("checksquareON");
        }

        else{
            $("#checksquare5").removeClass("checksquareON");
        }

        if(checksquare6save=="true"){
            $("#checksquare6").toggleClass("checksquareON");
        }

        else{
            $("#checksquare6").removeClass("checksquareON");
        }

        if(checksquare7save=="true"){
            $("#checksquare7").toggleClass("checksquareON");
        }

        else{
            $("#checksquare7").removeClass("checksquareON");
        }

        if(checksquare8save=="true"){
            $("#checksquare8").toggleClass("checksquareON");
        }

        else{
            $("#checksquare8").removeClass("checksquareON");
        }

        if(checksquare9save=="true"){
            $("#checksquare9").toggleClass("checksquareON");
        }

        else{
            $("#checksquare9").removeClass("checksquareON");
        }

        if(checksquare10save=="true"){
            $("#checksquare10").toggleClass("checksquareON");
        }

        else{
            $("#checksquare10").removeClass("checksquareON");
        }

        if(checksquare11save=="true"){
            $("#checksquare11").toggleClass("checksquareON");
        }

        else{
            $("#checksquare11").removeClass("checksquareON");
        }

        if(checksquare12save=="true"){
            $("#checksquare12").toggleClass("checksquareON");
        }

        else{
            $("#checksquare12").removeClass("checksquareON");
        }

        if(checksquare13save=="true"){
            $("#checksquare13").toggleClass("checksquareON");
        }

        else{
            $("#checksquare13").removeClass("checksquareON");
        }


        if(checksquare14save=="true"){
            $("#checksquare14").toggleClass("checksquareON");
        }

        else{
            $("#checksquare14").removeClass("checksquareON");
        }

        if(checksquare15save=="true"){
            $("#checksquare15").toggleClass("checksquareON");
        }

        else{
            $("#checksquare15").removeClass("checksquareON");
        }

我确实尝试过，但是没有用

I did try this but it didn't work

        for (i = 1; i <= 15; i++){
            if(checksquare + i + save=="true"){
                $("#checksquare" + i).toggleClass("checksquareON");
            }   
        }   

应该提到我上面有这些变量

Should have mentioned I have these vars above

        checksquare1save = localStorage['ScienceSkills-basicSkillsCheck-check1-7868-2171-1085-5119-4672'] 
        checksquare2save = localStorage['ScienceSkills-basicSkillsCheck-check2-6582-7209-6435-8487-6994']
        checksquare3save =  localStorage['ScienceSkills-basicSkillsCheck-check3-5367-9000-3502-5810-2295']
        checksquare4save = localStorage['ScienceSkills-basicSkillsCheck-check4-2961-8359-5106-2702-5132'] 
        checksquare5save = localStorage['ScienceSkills-basicSkillsCheck-check5-5801-5256-5838-2934-5277'] 
        checksquare6save = localStorage['ScienceSkills-basicSkillsCheck-check6-1162-2208-7274-5156-3693']
        checksquare7save = localStorage['ScienceSkills-basicSkillsCheck-check7-6178-4335-3148-1809-8066']
        checksquare8save = localStorage['ScienceSkills-basicSkillsCheck-check8-6609-6032-4539-4243-6273']
        checksquare9save =  localStorage['ScienceSkills-basicSkillsCheck-check9-6261-3580-7658-7073-1914']
        checksquare10save = localStorage['ScienceSkills-basicSkillsCheck-check10-1504-7246-1864-4465-1319']
        checksquare11save = localStorage['ScienceSkills-basicSkillsCheck-check11-6400-3954-7124-3585-2086']
        checksquare12save = localStorage['ScienceSkills-basicSkillsCheck-check12-8303-8392-7301-5154-8007']
        checksquare13save = localStorage['ScienceSkills-basicSkillsCheck-check13-1207-8834-5941-3315-8893']
        checksquare14save = localStorage['ScienceSkills-basicSkillsCheck-check14-3089-4036-1427-2614-7399']
        checksquare15save = localStorage['ScienceSkills-basicSkillsCheck-check15-2750-4976-5357-6403-2979'] 

推荐答案

如果您的变量在全局范围内，这应该可以工作:

This should work if your variables are in the global scope:

    for (i = 1; i <= 15; i++){
        if(window['checksquare' + i + 'save']=="true"){
            $("#checksquare" + i).toggleClass("checksquareON");
        }
        else{
            $("#checksquare" + i).removeClass("checksquareON");
        }
    }
