What is the best way to allocate values within a for loop?

Question

What is the best way to allocate values within a for loop?

I am in the process of designing an interface for individuals who have no background in programming. My goal is to allow them to input certain details, and then be able to simply copy and paste the code to make everything function seamlessly.

Here is a sample of the configuration object I am using:

var initSocialShare = {
  config: {
    facebook: false,
    linkedin: false,
    twitter: false,
    pocket: false,
    copy: false
  } 
}

My objective is to display this content inside a text area like so:

document.querySelector('#shareButton-code').innerHTML += 
   `<script> 
       var initSocialShare = {
           config: {
             facebook: ${obj},
             linkedin: ${obj},
             twitter: ${obj},
             pocket: ${obj},
             copy: ${obj}
          }
      } 
      ${initButtons} 
      ${showOverlay} 
      ${copyText} 
      initButtons()
</script>`;

How can I showcase the results of the loop within the script:

for (var key in initSocialShare.config) {
  // if (!initSocialShare.config.hasOwnProperty(key)) continue;

  var obj = initSocialShare.config[key];
  console.log(obj);
}

This section is part of my initialization method where I push the link to an array:

 if(initSocialShare.config.facebook){
    s.push( '"#" id="fs_facebook-btn" data-count="fb" onclick="window.open(\'https://www.facebook.com/sharer/sharer.php?u=' + u + "', '_blank', 'scrollbars=0, resizable=1, menubar=0, left=100, top=100, width=550, height=440, toolbar=0, status=0');return false\" title=\"Share on Facebook\"")
  }

Therefore, when users copy the code, this particular segment must function correctly.

Answer №1

You have the ability to iterate through substitutions within a template by utilizing a tagged template. Here is an example:

document.querySelector('#shareButton-code').innerHTML +=
  customTemplate`<script>
    var initSocialShare = {
      config: {
         facebook: ${initSocialShare},
         linkedin: ${initSocialShare},
         twitter: ${initSocialShare},
         pocket: ${initSocialShare},
         copy: ${initSocialShare}
      }
    }
  </script>`;

function customTemplate(literals, ...substitutions) {
  let result = '';
  let i = 0;

  for (const key in initSocialShare.config) {
    result += literals[i];
    result += initSocialShare.config[key];
    i++;
  }

  result += literals[literals.length - 1];
  return result;
}

UPDATED: (now includes all substitutions)

var initSocialShare = {
  config: {
    facebook: false,
    linkedin: false,
    twitter: false,
    pocket: false,
    copy: false
  }
}

const initButtons = 'foo';
const showOverlay = 'bar';
const copyText = 'baz';

document.querySelector('#shareButton-code').innerHTML +=
  customTemplate`<script>
    var initSocialShare = {
      config: {
         facebook: ${initSocialShare},
         linkedin: ${initSocialShare},
         twitter: ${initSocialShare},
         pocket: ${initSocialShare},
         copy: ${initSocialShare}
      }
    }
    ${initButtons}
    ${showOverlay}
    ${copyText}
    initButtons()
  </script>`;

function customTemplate(literals, ...substitutions) {
  let result = '';
  let i = 0;

  for (const key in initSocialShare.config) {
    result += literals[i];
    result += initSocialShare.config[key];
    i++;
  }

  for (let j = i; j < substitutions.length; j++) {
    result += literals[j];
    result += substitutions[j];
  }

  result += literals[literals.length - 1];
  return result;
}

    result += literals[j];
    result += substitutions[j];
  }

  result += literals[literals.length - 1];
  return result;
}

If you need to transform an Object into a string, you can create a helper function for it. Here's an example:

function makeObjString(obj) {

    let str = [];
    str.push('{');

    for(let k in obj) {
        str.push(k);
        str.push(':');
        str.push(obj[k]);
        str.push(',');
    }

    str.pop();

    str.push('}');

    return str.join('');
}

To use this function, simply call it like this:

document.querySelector('#shareButton-code').innerHTML += 
   `<script> 
       var initSocialShare = {
           config: ${makeObjString(initSocialShare.config)}
      } 
      ${initButtons} 
      ${showOverlay} 
      ${copyText} 
      initButtons()
</script>`;

This segment of code is part of my initialization method where I add a link to an array:

 if(initSocialShare.config.facebook){
    s.push( '"#" id="fs_facebook-btn" data-count="fb" onclick="window.open(\'https://www.facebook.com/sharer/sharer.php?u=' + u + "', '_blank', 'scrollbars=0, resizable=1, menubar=0, left=100, top=100, width=550, height=440, toolbar=0, status=0');return false\" title=\"Share on Facebook\"")
  }

Therefore, when the user copies the code snippet above, this particular section should function correctly.
