如何针对JSON使用JavaScript中的if条件？

Question

I have the following json file.

{
    "home_page_boolean":true,
    "syllabus_page_boolean":true,
    "schedule_page_boolean":true,
    "hws_page_boolean":true,
    "project_page_boolean":true,
    "banner_school_image_file":"",
    "left_footer_image_file":"",
    "right_footer_image_file":""
}

I'm trying to check wether one of the booleans is true or false. Notice that the way I have it now is that the value for the booleans is a boolean value and not a string value, (its not "project_page_boolean":"true")

This is what I tried,

if(data.homePageBoolean === true){
    navbar+= "<a id='home_link' class='open_nav' href='index.html'>Home</a>";
}

and

if(data.homePageBoolean.toString() === "true"){
    navbar+= "<a id='home_link' class='open_nav' href='index.html'>Home</a>";
}

but It doesn't work. I'm pretty sure the solution is simple but I can't figure it out

Answer 1

Try this

if(data['home_page_boolean']){
    navbar+= "<a id='home_link' class='open_nav' href='index.html'>Home</a>";
}

Answer 2

I think it should be as follows :

if(data.home_page_boolean === true){
    navbar+= "<a id='home_link' class='open_nav' href='index.html'>Home</a>";
}
