Jquery Set Cursor To Beginning Of Input Field On Focus
I have an input field and I want to make it so when a user focuses on this field, it will move the cursor to
Solution 1:
This will bind the focus
AND click
events of the input field to the function. Hope this helps!
$('#email').on('focus click', function() {
$(this)[0].setSelectionRange(0, 0);
})
<scriptsrc="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputtype="text"placeholder="Enter your name"autofocus><inputtype="text"id="email"value="@website.com">
Or, without jQuery...
document.getElementById('email').addEventListener('click', moveCursor);
document.getElementById('email').addEventListener('focus', moveCursor);
functionmoveCursor(event) {
event.target.setSelectionRange(0, 0);
}
<inputtype="text"placeholder="Enter your name"autofocus><inputtype="text"id="email"value="@website.com">
Solution 2:
Do you really need jQuery for this?
document.getElementById("email").addEventListener("click", moveCursor);
document.getElementById("email").addEventListener("focus", moveCursor);
functionmoveCursor(event) {
event.target.setSelectionRange(0,0);
}
<inputvalue="@website.com"type="text"name="email"id="email"></input>
Solution 3:
Whatever you want to perform with a cursor needs a field focus anyway.
Here is an old chunk I use. I even named it cursor.js
in a sub-directory... I took it from many places I guess.
It's a get/set cursor position. It takes a JS element. .oO($(el)[0]
for syntax loose..)
var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)var isFirefox = typeofInstallTrigger !== 'undefined'; // Firefox 1.0+var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
// At least Safari 3+: "[object HTMLElementConstructor]"var isChrome = !!window.chrome && !isOpera; // Chrome 1+var isIE = /*@cc_on!@*/false || !!document.documentMode; // At least IE6functionGetCursorPos (field) {
// Initialize
iCaretPos = 0;
if (isIE){
// Set focus on the element
field.focus();
// To get cursor position, get empty selection range
oSel = field.createTextRange();
// Move selection start to 0 position
oSel.moveStart('character', -field.value.length);
// The caret position is selection length
iCaretPos = oSel.text.length;
}
if (isChrome||isSafari){
iCaretPos = field.selectionStart;
}
if (isFirefox){
iCaretPos = field.selectionStart;
}
return iCaretPos;
}
functionSetCursorPos (field,Pos) {
// Set focus on the element
field.focus();
if (isIE){
field.selectionStart=Pos;
}
if (isChrome||isSafari){
field.setSelectionRange(Pos,Pos);
}
if (isFirefox){
field.selectionStart=Pos;
}
return;
}
About browser-friendly considerations, there is:
.selectionStart
-- Chrome/Safari/Firefox.setSelectionRange(Pos,Pos)
-- Chrome/Safari/Firefox/Internet Explorer.createTextRange()
-- Internet Explorer
An inspiration I used upthere long ago: partial (compared to the above) SO answer
