Hello,

i have a dropdown column with few values and there is "Other" one of the value. So as soon as user select "Other" value from the drop-down another text box will pop-up on the form. it was working before on the form but all of a sudden not displaying the text box. is there any idea what could be the issue?

$(document).ready(function () {
    MyFieldChanged();
    $('#custom_preference').on("change", MyFieldChanged);
});

function MyFieldChanged() {
  $("#custom_text").closest("tr").hide();
    var selectedValue = $('#custom_preference').val();
    if (!!selectedValue && selectedValue == 881990007) {
      $("#custom_text").closest("tr").show();
    }
    else {
      $("#custom_text").closest("tr").hide();
    }
}

Hi Rakki,

I tested your code on my side and it could work fine.

Below is my test:

1. Add JS code to my basic form.

Result:

You can try the following points:

1. Clear the cache of your browser and reopen your portal.

2. Press F12 to see there is any error.

3. Debugger your code to see that does it run well.

Hi Rakki,

You could add debugger; or console.log(object) in you code. Something like this:

$(document).ready(function () { MyFieldChanged(); $('#custom_preference').on("change", MyFieldChanged); }); function MyFieldChanged() { debugger; $("#custom_text").closest("tr").hide(); console.log($("#custom_text").closest("tr")); var selectedValue = $('#custom_preference').val(); if (!!selectedValue && selectedValue == 881990007) { $("#custom_text").closest("tr").show(); } else { $("#custom_text").closest("tr").hide(); } }

Then press F12 to debug or view the console.

Hi Rakki,

Based on the screenshot you provide, the issue should cause by your filed name is wrong. Please change $('#les_Perference').val() to $('#les_perference').val() at line426 in your screenshot.(The P should be lower case as the same as it at the line419)

Hello Steve,

Still "Others" text box not showing up on the form even though Other option value is getting "100000007" when selected from the drop-down as you can see in the below picture. what else causing the issue you think?

Appreciated for your help.

Hi Rakki,

Based on your code, it should work if your logical name "#les_others" is correct. You could press f12 to check it.

And I noticed that the other would show whatever your if condition is true or false.

Please change to code like this:

if(selectedValue && selectedValue == 100000007){
console.log(true);
$("#les_others").closest("tr").show();
}
else{
console.log(false);
$("#les_others").closest("tr").hide();
}

And you could know which branch is executed by the output in console. Please clear your cache to have a try.
