Is there a way to get innerText of only the top element (and ignore the child element\'s innerText) ?
Example:
top node text
<
If you don't want to ignore the child element's inner text, use the following function:
function getInnerText(el) {
var x = [];
var child = el.firstChild;
while (child) {
if (child.nodeType == 3) {
x.push(child.nodeValue);
}
else if (child.nodeType == 1) {
var ii = getInnerText(child);
if (ii.length > 0) x.push(ii);
}
child = child.nextSibling;
}
return x.join(" ");
}
function getDirectInnerText(element) {
var childNodes = element.childNodes;
result = '';
for (var i = 0; i < childNodes.length; i++) {
if(childNodes[i].nodeType == 3) {
result += childNodes[i].data;
}
}
return result;
}
element = document.querySelector("div#element");
console.log(getDirectInnerText(element))
<div id="element">
top node text
<div> child node text </div>
</div>
This will work in your example:
document.getElementById("item").firstChild.nodeValue;
Note: Keep in mind that this will work if you know you are dealing with that specific HTML. If your HTML can change, for example to:
<div>
<div class="item"> child node text </div>
top node text
</div>
then you should use the more generic solution by @Tim Down
Here is working code snippet:
window.onload = function() {
var text = document.getElementById("item").firstChild.nodeValue;
document.getElementById("result").innerText = text.trim();
};
#result {
border: 1px solid red;
}
<div id="item">
top node text
<div> child node text </div>
</div>
<strong>Result:</strong> <div id="result"></div>
Just iterate over the child nodes and concatenate text nodes:
var el = document.getElementById("your_element_id"),
child = el.firstChild,
texts = [];
while (child) {
if (child.nodeType == 3) {
texts.push(child.data);
}
child = child.nextSibling;
}
var text = texts.join("");
tagName
attribute, then it's an element: Remove the node.innerText
to get the textual contents (with fallback to textContent
, when innerText
is not supported).Code:
var elem = document.getElementById('theelement');
elem = elem.cloneNode(true);
for (var i=elem.childNodes.length-1; i>=0; i--) {
if (elem.childNodes[i].tagName) elem.removeChild(elem.childNodes[i]);
}
var innerText = elem['innerText' in elem ? 'innerText' : 'textContent'];
