JavaScript get textContent excluding children

Question

First, I'm creating a library for JavaScript and I can not use jQuery. I'm trying to get the text content of an HTML element without the text contents of its children.

Both attributes innerText and textContent don't give me what needed, please help.

Answer 1

You can solve using DOM API as childNodes and nodeType.

var elChildNode = document.querySelector("#hello").childNodes;
var sChildTextSum = "";

elChildNode.forEach(function(value){
    if(value.nodeType === Node.TEXT_NODE) { 
        console.log("Current textNode value is : ", value.nodeValue.trim());
        sChildTextSum += value.nodeValue;
    }
}); 

console.log("All text value of firstChild : ", sChildTextSum);

I created a sample code as above.

Answer 2

var mydiv = getElementByID("id");
function Get_text(element) {
    var selected = element.cloneNode(true);
    var text;
    while (selected.firstChild) {
      if (selected.firstChild.nodeType == 3) text = selected.firstChild.nodeValue;
      selected.removeChild(selected.firstChild);
    }
    return text;
  }
Get_text(mydiv);
