What is the best way to add a new element with specified text to a group of chosen HTML elements?

Here is some HTML code that selects specific elements:

let array = jQuery.makeArray($(".dersprg tr td:nth-child(6)"));

The selected elements contain table header text and some irrelevant data. While I can interpret the irrelevant data using if statements and extract the necessary information, I encounter an issue when trying to push it to the array due to types not matching. The code snippet is shown below:

for(let i=0; i<array.length; i++){
    let content = array[i].innerHTML;
    if(some conditions){
        array.splice(i--,1);    //eliminate non day elements
        array.push('test input <br>');  //problematic line
    }
}

As you can see, I utilize innerHTML to compare the content of the selected <td> element, but adding some test input results in the entire array becoming empty. I suspect this is due to a type mismatch, but I am unsure how to address this issue. Any assistance would be greatly appreciated.

Answer №1

Give this a shot:

let element = document.createElement('td');
element.appendChild( document.createTextNode('testing input <br>') );
collection.push(element);

By using this code snippet, you can add a <td> element to the collection instead of just a plain string.
