Does chrome supports document.selection?

Question

I am new to javascript, trying to perform:

document.selection.createRange();

but document.selection always returns undefined.

I am using latest version of chrome.

what am I doing wrong?

thanks!

Answer 1

Use window.getSelection(), which is the most cross-browser compatible (it's supported in the current versions of all major browsers) and is the standard. Chrome certainly supports it as fully as other browsers.

document.selection should only be used for IE < 9.

IE9 doesn't like it : SCRIPT438: Object doesn't support property or method 'getSelection' – Irrepressible

@Misi: In which case your IE 9 must be in one of the compatibility modes. In standards mode, it definitely supports window.getSelection(). msdn.microsoft.com/en-us/library/ie/… – Aiglet

Answer 2

Try document.getSelection() or window.getSelection().

Here's a quick example that I tested in chrome

i've tried using both window.getSelection and Document.getSelection but also the function getRangeAt(index) does not functioning. i've done: var selObj = document.getSelection(); var selRange = selObj.getRangeAt(0); alert(selRange); what do you say? thanks – Susannasusannah

im getting rangeCount value always zero – Susannasusannah

@Susannasusannah I've added an example that was test in chrome – Abradant

I assume selection is just the class of the object which is retrieved with document.getSelection() like below: var s = document.getSelection(); s."Any of properties or methods listed in link below"; developer.mozilla.org/en-US/docs/Web/API/Selection – Gisborne

Answer 3

Browser support for the selection object based on IE11 and Chrome 87.04280.141

Member	IE	Chrome
document.selection	yes	no
window.selection	no	no
document.getSelection()	no	yes
window.getSelection()	no	yes

This is the easy part. The problems come when you are trying to use any methods, f.e. getRange() which exists for document.selection (IE compatible), but doesn't exist for document.getSelection(), so for Chrome you need a workaround.

Casement

mm... it seems like IE supports both window and document's getSelection methods - are you sure about the browser support table? – Moonrise

Answer 4

Use window.getSelection() instead.
