    if (document.selection) {
        var range = document.body.createTextRange();
        range.moveToElementText(document.getElementById(containerid));
        range.select();
    } else if (window.getSelection) {

        range.selectNode(document.getElementById(containerid));
        window.getSelection().addRange(range);

Hi @mymac1, you might remove all ranges from the selection if the selection already contains the container; actually it would make sense to empty the selection anyway in case the user already selected some text inside the container, as merging ranges won’t work. For example:

function selectText (containerId) {
  var selection = window.getSelection()
  var container = document.getElementById(containerId)
  var isContainerSelected = selection.containsNode(container)
  var range = document.createRange()

  selection.removeAllRanges()

  if (!isContainerSelected) {
    range.selectNode(container)
    selection.addRange(range)
  }
}

IDK it works for me. Are there any errors in the browser console?

No error in console but…

I make this observation
after pressing again Selects it only if mouse clicked on the DIV

eg if text on the left clicked on the right **but in the DIV on the right** after pressing again fails re-selects it — is like button Not function…WHEN PRESS ABOVE OR BELOW THE DIV in other words Not pressing on the div itself...

well

BTW I am using jQuery Mobile and its swipe functionality…

console chrome

No error in console but…

I make this observation
after pressing SELECT BUTTON again TEXT Selected it only if mouse clicked before (to deselect it) on the containing DIV

after pressing again fails re-selects it — is like button Not function…WHEN PRESS ABOVE OR BELOW THE DIV in other words NOT pressing on the CONTAINING div itself…
well
