Is it possible to transform a string into a variable?

Question

Is it possible to transform a string into a variable?

I have 4 variables containing different strings, and I would like to use a for-loop to create a table and populate the cells with these strings. However, when I run my current code, I end up with "content1", "content2", etc. instead of the actual content stored in the variables content1, content2, and so on. Is there a way to convert the generated strings (e.g., "content1") back to the original variables? If yes, how can this be achieved?

var content1 = "Text1";
var content2 = "Text2";
var content3 = "Text3";
var content4 = "Text4";

for (var i = 1; i < 5; i++){        
    var td = document.createElement('td');
    var text = document.createTextNode("content" + [k]);
    td.appendChild(text);
    tr.appendChild(td);
}

table.appendChild(tr);

Answer 1

Answer №1

Consider utilizing window['content' + k] as an alternative solution, but it is advisable to reconsider your approach in order to avoid the use of variable variables. They can result in complex and challenging-to-debug code.

As a basic step, transitioning to an array structure would be beneficial:

content = ['', 'Text1', 'Text2', 'Text3', 'Text4']; // Initialize with empty string to occupy the '0' index

alert(content[1]); // This will display Text1

Affirmative.

let items = ["One", "Two", "Three", "Four"];

for (let index = 0; index < items.length; index++){        
    let tdCell = document.createElement('td');
    let textNode = document.createTextNode( items[index] );
    tdCell.appendChild(textNode);
    tableRow.appendChild(tdCell);
}

dataTable.appendChild(tableRow);

If you're dealing with a situation like this, one approach could be to utilize an array for storing your strings:

let contentArray = ['String1', 'String2', 'String3', 'String4'];

Then, at a later point:

let textNode = document.createTextNode(contentArray[i+1]);

Alternatively, although not recommended, you could use the eval function:

eval("let dynamicText = contentArray" + (i+1));
let textNode = document.createTextNode(dynamicText);

However, keep in mind that the eval method comes with risks and is generally considered unreliable.

Utilizing an array to generate content is a proven method.

var contentArray = new Array();

contentArray[0] = "First Text";
contentArray[1] = "Second Text";
contentArray[2] = "Third Text";

for (var j = 1; j < 5; j++){        
    var cell = document.createElement('td');
    var textNode = document.createTextNode("Content: " + contentArray[j]);
    cell.appendChild(textNode);
    row.appendChild(cell);
}

table.appendChild(row);

When tackling assignments, it's beneficial to organize your variables in a centralized array:

Consider using a "content" array for this purpose:

let content = ["Text1", "Text2", ...];

You can then easily access the elements by iterating through the array like content[i]

for (let i = 0; i < content.length; i++){...}

Hopefully this tip proves useful!
