The example in this article describes the method of JS to obtain and set the TextArea or input text box to select the text position. Share it with everyone for your reference. The specific implementation method is as follows:
function getPos(el) { var range, textRange, duplicate el.focus() if ( el.selectionStart ) return el.selectionStart else if ( document.selection ) { // IE range = document.selection.createRange() if ( range == null ) return el.value.length textRange = el.createTextRange() duplicate = textRange.duplicate() textRange.moveToBookmark(range.getBookmark()) duplicate.setEndPoint('EndToStart', textRange) return duplicate.text.length } } function setPos(el, pos) { var range el.focus() if ( el.setSelectionRange ) el.setSelectionRange(pos, pos) else if ( el.createTextRange ) { range.collapse(true) range.moveEnd('character', pos) range.moveStart('character', pos) range.select() } }
I hope this article will be helpful to everyone’s JavaScript programming design.
