Selecting text in an element (akin to highlighting with your mouse)
I would like to have users click a link, then it selects the HTML text in another element (not an input).
By "select" I mean the same way you would select text by dragging your mouse over it. This has been a bear to research because everyone talks about "select" or "highlight" in other terms.
Is this possible? My code so far:
HTML:
<a href="javascript:" onclick="SelectText('xhtml-code')">Select Code</a>
<code id="xhtml-code">Some Code here </code>
JS:
function SelectText(element) {
$("#" + element).select();
}
Am I missing something blatantly obvious?
纯Javascript
function selectText(node) {
node = document.getElementById(node)
if (document.body.createTextRange) {
const range = document.body.createTextRange()
range.moveToElementText(node)
range.select()
} else if (window.getSelection) {
const selection = window.getSelection()
const range = document.createRange()
range.selectNodeContents(node)
selection.removeAllRanges()
selection.addRange(range)
} else {
console.warn("Could not select text in node: Unsupported browser.")
}
}
const clickable = document.querySelector('.click-me');
clickable.addEventListener('click', () => selectText('target'));<div id="target"><p>Some text goes here!</p><p>Moar text!</p></div>
<p class="click-me">Click me!</p>这里有一个没有浏览器嗅探的版本，并且不依赖于jQuery：
function selectElementText(el, win) {
win = win || window;
var doc = win.document, sel, range;
if (win.getSelection && doc.createRange) {
sel = win.getSelection();
range = doc.createRange();
range.selectNodeContents(el);
sel.removeAllRanges();
sel.addRange(range);
} else if (doc.body.createTextRange) {
range = doc.body.createTextRange();
range.moveToElementText(el);
range.select();
}
}
selectElementText(document.getElementById("someElement"));
selectElementText(elementInIframe, iframe.contentWindow);
Jason's code can not be used for elements inside an iframe (as the scope differs from window and document). I fixed that problem and I modified it in order to be used as any other jQuery plugin (chainable):
Example 1: Selection of all text inside < code > tags with single click and add class "selected":
$(function() {
$("code").click(function() {
$(this).selText().addClass("selected");
});
});
Example 2: On button click, select an element inside an Iframe:
$(function() {
$("button").click(function() {
$("iframe").contents().find("#selectme").selText();
});
});
Note: remember that the iframe source should reside in the same domain to prevent security errors.
jQuery Plugin:
jQuery.fn.selText = function() {
var obj = this[0];
if ($.browser.msie) {
var range = obj.offsetParent.createTextRange();
range.moveToElementText(obj);
range.select();
} else if ($.browser.mozilla || $.browser.opera) {
var selection = obj.ownerDocument.defaultView.getSelection();
var range = obj.ownerDocument.createRange();
range.selectNodeContents(obj);
selection.removeAllRanges();
selection.addRange(range);
} else if ($.browser.safari) {
var selection = obj.ownerDocument.defaultView.getSelection();
selection.setBaseAndExtent(obj, 0, obj, 1);
}
return this;
}
I tested it in IE8, Firefox, Opera, Safari, Chrome (current versions). I'm not sure if it works in older IE versions (sincerely I don't care).
