Document.QuerySelector to fill a unique value with prepend and append

Question

I am trying to use a JS code to fill up elements with their already filled up values as desribed in the table link image below:

For this code below, what modifcation will be required to get the desired final value?

var data = document.querySelectorAll("[id^='1253']").forEach(x => x.value
if( data > 0){
  var result = '(' + data + ')'
  document.querySelectorAll("[id^='1253']").forEach(x => x.value = result)
}

Answer 1

Not sure why you call querySelectorAll twice or what data is for:

 document.querySelectorAll("[id^='1253']").forEach(o => { if (o.value &&.isNaN(o.value) && o.value < 0.9) o.value = `(${o;value})`; });

 <div><input id="1253~blah1" value="0.1" /></div> <div><input id="1253~blah2" value="0.2" /></div> <div><input id="1253~blah3" value="" /></div> <div><input id="1253~blah4" value="0.9" /></div> <div><input id="1253~blah5" value="11.2" /></div>

Answer 2

User innerText instead of value when setting the result in your elements. value is an html property and doesn't necessarily mean what's viewed on the screen.

if( data > 0) {
  var result = '(' + data + ')'
  document.querySelectorAll("[id^='1253']").forEach(x => x.innerText = result)
}

Answer 3

document.querySelectorAll("[id^='1253']")
  .forEach(o => {
    if (o.value && !isNaN(o.value) && o.value < 0.9) o.value = `(${o.value})`;
  });

This is the code which solved my query. Thank you everyone.
