I have a web form with a text box in it. How do I go about setting focus to the text box by default?
Something like this:
<body onload='setFocusToTextBox()'>
so can anybody help me with it? I don't know how to set focus to the text box with JavaScript.
<script>
function setFocusToTextBox(){
//What to do here
}
</script>
Do this.
If your element is something like this..
<input type="text" id="mytext"/>
Your script would be
<script>
function setFocusToTextBox(){
document.getElementById("mytext").focus();
}
</script>
Document.forms, Document.getelementsByTagName or Node.childNodes) and either rely on a known document structure or look for some element specific properties.
For what it's worth, you can use the autofocus attribute on HTML5 compatible browsers. Works even on IE as of version 10.
<input name="myinput" value="whatever" autofocus />
autofocus.
Usually when we focus on a textbox, we should also scroll into view
function setFocusToTextBox(){
var textbox = document.getElementById("yourtextbox");
textbox.focus();
textbox.scrollIntoView();
}
Check if it helps.
If your code is:
<input type="text" id="mytext"/>
And If you are using JQuery, You can use this too:
<script>
function setFocusToTextBox(){
$("#mytext").focus();
}
</script>
Keep in mind that you must draw the input first $(document).ready()
egregiously sloppy, no-effort-expended post, or an answer that is clearly and perhaps dangerously incorrect, according to stackoverflow's help center. I find this nowhere near those categories. Helping is not limited to the OP, is it?For plain Javascript, try the following:
window.onload = function() {
document.getElementById("TextBoxName").focus();
};
I used to just use this:
<html>
<head>
<script type="text/javascript">
function focusFieldOne() {
document.FormName.FieldName.focus();
}
</script>
</head>
<body onLoad="focusFieldOne();">
<form name="FormName">
Field <input type="text" name="FieldName">
</form>
</body>
</html>
That said, you can just use the autofocus attribute in HTML 5.
Please note: I wanted to update this old thread showing the example asked plus the newer, easier update for those still reading this. ;)
window.onload is to put focus initially onblur is to put focus while you click outside of the textarea,or avoid text area blur
<textarea id="focus"></textarea>
<script>
var mytexarea=document.getElementById("focus");
window.onload=function() {
mytexarea.focus();
}
</script>
As mentioned earlier, document.forms works too.
function setFocusToTextBox( _element ) {
document.forms[ 'myFormName' ].elements[ _element ].focus();
}
setFocusToTextBox( 0 );
// sets focus on first element of the form
If your <input> or <textarea> has attribute id=mytext then use
mytext.focus();
function setFocusToTextBox() {
mytext.focus();
}<body onload='setFocusToTextBox()'>
<form>
<input type="text" id="mytext"/>
</form>
</body>
this example worked for me
$(document).ready(function () {
document.getElementById('TextBox').focus();
}
<input type="text" class="word"> //html code
let theinput = document.querySelector(".word"); //Get the input
theinput.focus(); // focus on input
Thought of sharing some edge cases for this subject. If your content is reloading (example dynamic DOM loading results from API and setting focus on first item of results) adding attribute autofocus will not be your solution, it works only on first load, second DOM change will not work but works fine in static DOM or single page load. If you have Dynamic component loading data simple .focus() will fail due to triggering focus on element not created yet by the time focus() is or blur not complete yet by DOM. For this case expected is to add delay time (setTimeout function) to give a time for focus to apply to new created or recreated element in DOM. My case was to load data from API and get focus on first result. Adding
//focusId is ID of element you need focus on
var el = document.getElementById(focusId);
el.focus();
solved the issue so DOM completes blur without adding delay.
Try This:
$('.modal').on('shown.bs.modal', function () {
setTimeout(function() {
$("input#yourFieldId").addClass('modal-primary-focus').focus();
}, 500);
});
document.getElementById('your_text_box_id').focus();.autofocuson the html input tag is often enough.
