如何使用Javascript将Json与字符串匹配

Question

What I need to do:

• I need to match Json with string .

case 1: When industry data is set in Json

        ["", "app.php", "automotive", "tradeshows"]

JQuery code:

  $( document ).ready(function() 
 {


    var match =  window.location.pathname.split("/");
    console.log(match[3]);

    if(match[3]=="conferences")
    {
         console.log("true");
    $('#radio3').prop('checked', true);

    }
    else if(match[3]=="tradeshows")
    {
        console.log("afeef");
        $('#radio2').prop('checked', true);
    }
    else
    {
        $('#radio1').prop('checked', true);
    }



   });

case 2: When industry data is not set in Json

     ["", "app.php",  "tradeshows"]

• In this case match would be failed.

• Is there any other way in match Json with string in JQuery?

• I need to match the Json with string so is there any other way so that I could match Json with string ?

Answer 1

You can use jQuery indexOf() to detect if automotive is available or not. See the below code

 function myFunction(page) { var pages = ["", "app.php", "automotive", "tradeshows"]; var a = pages.indexOf(page); document.getElementById("demo").innerHTML = a; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <p>Click the button to display the position of the element "tradeshows":</p> <button onclick="myFunction('automotive')">Check for automotive</button> <button onclick="myFunction('automotive1')">Check for automotive1</button> <p id="demo"></p> 

Note: The indexOf method was introduced in JavaScript 1.6, and does not work in Internet Explorer 8 and earlier versions.
