So I've looked around at doing this as I need to get around an iOS bug, and none of my simulated clicks seem to work. I'm trying to manually focus on a textarea element but to do that I need to manually simulate a click on said textarea element. So here's what I've tried:
$('#text-input')[0].click();
$('#text-input').click();
$('#text-input').trigger('click');
$('#text-input').focus();
and
$('#text-input').on('click', function {
$(this).focus();
});
$('#text-input').trigger('click');
$('#text-input').on('touchstart', function {
$(this).focus();
});
$('#text-input').trigger('touchstart');
HTML:
<textarea id="comment-input" class="comment-input" rows="1" maxlength="{{maxTextLength}}" ng-model="newMessage.content" placeholder="{{ messagePlaceholder }}" />
Any thoughts on why this isn't working?
try .focus instead of click like
$('#text-input').trigger('focus');
or Just
$('#text-input').focus();
UPDATE
You can try setTimeout which works in most case
$("#text-input").on("click", function(event) {
setTimeout(function() {
$(event.target).select(); //or $(event.target).focus();
}, 1);
});
UPDATE 2
You can also try to use touchstart event like
//trigger touch on element to set focus
$("#text-input").trigger('touchstart');
//event handler to set the focus()
$('#text-input').on('touchstart', function () {
$(this).focus(); // inside this function the focus works
});

I'm attempting to prevent a user from clicking a link and it going to another page while any input is focused. Sometimes the only available space around the input and the keyboard is a link and some users click the link accidentally. I'm trying to make it so when they click the link it blurs the input (closes the keyboard) and prevents the page from following the link. Then let them click the link again if they want to go to another page after the input is no longer in focus.
html
<input type="text">
Example
I've tried the following...
jQuery
$('a').on('click', function (event) {
if ($('input').is(":focus")) {
console.log('focused');
event.preventDefault();
}
});
(nothing gets logged)
Also tried this...
if ($('input').is(":focus")) {
$('a').on('click', function (event) {
event.preventDefault();
$('input').each(function(){
$(this).trigger('blur');
});
});
}
Neither one prevent the page from going to whatever link was clicked...
I don't think you can do this. You can disable the click event on the links while input is focused, and enable it back again when blur occurs on the input elements. However, while if user clicks on a link while focused on the input element blur event will occur first (which would enable clicking) then click even occurs and links acts as normal.
You could try disabling the links while input elements have focus, then you can enable them on the first click and restore normal operation.
$("input").on("focus", function() {
$("a").on("click", function (event) {
event.preventDefault();
$("a").off();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
example
I think I found a solution.
HTML
Example.com
jQuery
$('input').on('focus', function () {
$('a').each(function(){
$(this).addClass('cant-click');
});
});
$(document).on('touchend', function (e) {
if (!$(e.target).closest('input').length) {
$('a').each(function(){
$(this).removeClass('cant-click');
});
}
});
CSS
a.cant-click { pointer-events: none; }
When the input takes focus, every link gets this class. When anything on the page is clicked that is not an input, it removes this class from every link.
I'm working on a project with an autocomplete searchbox. Now I have the issue that I want to pass the value from the found autocompleteresults to the input box, but on the same time, I want the autocompletebox to hide when the inputfield is not more focused.
Now I have a conflict going on with both of them since the click on the autocompletebox is seen as focusout and hide the box even before it can pass the value. Any pointers or workarounds for this kind of issue? Here a jsfiddle to make it more clear to you.
http://jsfiddle.net/KeGvM/
Or here
CSS:
#a_c {display:none;}
JS:
$('#search_field').focusout(function() {
$('#a_c').hide(); // IF I DELETE THIS IT WORKS
});
$('#search_field').focusin(function() {
$('#a_c').show();
});
$('#a_c a').click(function() {
$('#search_field').val('');
var value = $(this).text();
var input = $('#search_field');
input.val(input.val() + value);
$('#a_c').hide();
return false;
});
HTML:
<input autocomplete="off" onkeyup="searchFor(this.value);" name="search" id="search_field" class="bold" type="text" placeholder="Search...">
<div id="a_c">hello world</div>
The way I solved this was using the mousedown event instead of click. The mousedown event is always triggered before the focusout event while click is not.
You can try it out in the little demo below. Focus on the field and then click on the button.
const field = document.getElementById('field');
const btn = document.getElementById('btn');
btn.addEventListener('click', () => console.log('Click'));
btn.addEventListener('mousedown', () => console.log('Mouse down'));
field.addEventListener('focusout', () => console.log('Focus out'));
<input id="field">
<button id="btn">Try it</button>
As you can see the output is in the following order:
Mouse down
Focus out
Click
This is the most stable solution without using any workaround hacks like timeouts. It also does not depend on jQuery. The only thing worth noting that mousedown does not wait for the user to release their mouse button, but in terms of user experience that is not really a concern here.
How about using
:hover
I solved same problem using it.
$('className').on('focusout', function(e) {
if($('.suggestLi' + ':hover').length) {
return;
}
$('.suggestList').empty();
});
My solution in the similar situation was using timeout to temporarily hold off the action taken in blur event handler. Like this:
$('#search_field').focusout(function() {
window.setTimeout(function() { $('#a_c').hide() }, 100);
});
I have the following html code:
<input type="text" id="theInput" value=""/>
Click me
I want to detect when the input changes and perform an operation in this case, but ONLY when the user has not clicked in the link. I have tried this:
$('#theLink').live('click', function(){
alert('click');
});
$('#theInput').live('change', function(){
alert('change');
});
However change is always executed before click when the value in the input changed, due to Javascript event precedence rules, and therefore only "change" message is displayed.
I would like it to display change only if the input value changed and the user exited the input clicking in any other place instead of the link. In that last case I would like to display click.
The example is here.
I use jQuery 1.6.4.
As far as I know, the click event fires after the blur and change events in every browser (have a look at this JSFiddle). The order of blur and change is different across browsers (source: Nicholas Zakas).
To solve your problem, you could listen to click events on the document and compare the event's target with #theLink. Any click event will bubble up to the document (unless it is prevented).
Try this:
var lastValue = '';
$(document).click(function(event) {
var newValue = $('#theInput').val();
if ($(event.target).is('#theLink')) {
// The link was clicked
} else if (newValue !== lastValue) {
// Something else was clicked & input has changed
} else {
// Something else was clicked but input didn't change
}
lastValue = newValue;
});
JSFiddle: http://jsfiddle.net/PPvG/TTwEG/
Both events will fire but in your example the alert in the onchange event handler fired when the onmousedown event occurs will stop the onmouseup event required for the onclick event to fire. Using console.log will show both events firing.
http://jsfiddle.net/hTqNr/4/
Ok, now i got it, you could do
$('#theLink').live('click', function(e){
alert('click');
});
$('#theInput').live('change', function(e){
//Check if the change events is triggerede by the link
if(e.originalEvent.explicitOriginalTarget.data === "Click me"){
//if this is the case trigger the click event of the link
$('#theLink').trigger("click");
}else{
//otherwise do what you would do in the change handler
alert('change');
}
});
Fiddle here http://jsfiddle.net/hTqNr/19/
why you dont pick the value of input box. you have to store initial value of input box on ready function
initialvalue= $('#theInput').val();
then compare the value
$('#theLink').live('click', function(){
var newvalue =$('#theInput').val();
if(newvalue!=initialvalue) {
//do something
}
});
Then the user uses TAB or SHIFT-TAB to "jump" to a certain text-box and that text-box happens to have a value in it, then that value will be auto-selected. I would like to disable this behavior.
I assume that can be done inside the focusin event handler:
$("input:text").focusin(function() {
// "un-select" the value and place the text-cursor
// at the beginning or end of the value
});
$(function() {
$('input').bind('focus', function(e) {
return false;
});
});
Using jQuery 1.4.3+ you can use the shortcut version:
$(function() {
$('input').bind('focus', false);
});

I have the same problem as the user in this question, which is due to this bug in Webkit. However, the workaround provided will not work for my app. Let me re-state the problem so that you don't have to go read another question:
I am trying to select all the text in a textarea when it gets focus. The following jQuery code works in IE/FF/Opera:
$('#out').focus(function(){
$('#out').select();
});
However, in Chrome/Safari the text is selected--very briefly--but then the mouseUp event is fired and the text is deselected. The following workaround is offered in the above links:
$('#out').mouseup(function(e){
e.preventDefault();
});
However, this workaround is no good for me. I want to select all text only when the user gives the textarea focus. He must then be able to select only part of the text if he chooses. Can anyone think of a workaround that still meets this requirement?
How about this?
$('#out').focus(function () {
$('#out').select().mouseup(function (e) {
e.preventDefault();
$(this).unbind("mouseup");
});
});
The accepted answer (and basically every other solution I found so far) does not work with keyboard focus, i. e. pressing tab, at least not in my Chromium 21. I use the following snippet instead:
$('#out').focus(function () {
$(this).select().one('mouseup', function (e) {
$(this).off('keyup');
e.preventDefault();
}).one('keyup', function () {
$(this).select().off('mouseup');
});
});
e.preventDefault() in the keyup or focus handler does not help, so the unselecting after a keyboard focus seems to not happen in their default handlers, but rather somewhere between the focus and keyup events.
As suggested by #BarelyFitz, it might be better to work with namespaced events in order to not accidentally unbind other event handlers. Replace 'keyup' with 'keyup.selectText' and 'mouseup' with 'mouseup.selectText' for that.
Why not simply:
$('#out').focus(function(){
$(this).one('mouseup', function() {
$(this).select();
});
});
Seems to work in all major browsers...
A very slightly different approach would be to separate the focus event from the mouse sequence. This works really nicely for me - no state variables, no leaked handlers, no inadvertent removal of handlers, and it works with click, tab, or programmatic focus. Code and jsFiddle below -
$('#out').focus(function() {
$(this).select();
});
$('#out').on('mousedown.selectOnFocus', function() {
if (!($(this).is(':focus'))) {
$(this).focus();
$(this).one('mouseup.selectOnFocus', function(up) {
up.preventDefault();
});
}
});
https://jsfiddle.net/tpankake/eob9eb26/27/
Make a bool. Set it to true after a focus event and reset it after a mouse up event. During the mouse up, if it's true, you know the user just selected the text field; therefore you know you must prevent the mouse up from happening. Otherwise, you must let it pass.
var textFieldGotFocus = false;
$('#out').focus(function()
{
$('#out').select();
textFieldGotFocus = true;
});
$('#out').mouseup(function(e)
{
if (textFieldGotFocus)
e.preventDefault();
});
$(document).mouseup(function() { textFieldGotFocus = false; });
It's important that you put the mouseup listener that resets the variable on document, since it's not guaranteed that the user will release the mouse button over the text field.
onclick="var self = this;setTimeout(function() {self.select();}, 0);"
Select the text before putting the focus on the input box.
$('#out').select().focus();
digitalfresh's solution is mostly there, but has a bug in that if you manually trigger .focus() using JS (so not using a click), or if you tab to the field, then you get an unwanted mouseup event bound - this causes the first click that should deselect the text to be ignored.
To solve:
var out = $('#out');
var mouseCurrentlyDown = false;
out.focus(function () {
out.select();
if (mouseCurrentlyDown) {
out.one('mouseup', function (e) {
e.preventDefault();
});
}
}).mousedown(function() {
mouseCurrentlyDown = true;
});
$('body').mouseup(function() {
mouseCurrentlyDown = false;
});
Note: The mouseup event should be on body and not the input as we want to account for the user mousedown-ing within the input, moving the mouse out of the input, and then mouseup-ing.
tpankake's answer converted to a reusable jQuery function..
(If you upvote this, please also upvote his answer)
Load the following AFTER loading the jQuery library:
$.fn.focusSelect = function () {
return this.each(function () {
var me = $(this);
me.focus(function () {
$(this).select();
});
me.on('mousedown.selectOnFocus', function () {
var me2 = $(this);
if (me2.is(':focus') === false) {
me2.focus();
me2.one('mouseup.selectOnFocus', function (up) {
up.preventDefault();
});
}
});
});
};
Use it like this:
$(document).ready(function () {
// apply to all inputs on the page:
$('input[type=text]').focusSelect();
// apply only to one input
$('#out').focusSelect();
});
