two event handlers (click and mousemove) at the same time on one element
I'm creating a sort of slider which when a certain point on the window is clicked the element will stretch its width to that point. I would also like to add a drag event handler and I have read about mousedown and mousemove and mouseup being the three handlers that need to be combined. This code works quite well but I'm wondering is there a better way to combine these handlers because at the moment I am repeating code whihc Im not sure is necessary. I'm quite new to javascript and jquery. Thanks for the help
function reposition_bar(mouse_touch_position){
document.onclick = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
document.onmousemove = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
this.onmouseup = function() {
document.onmousemove = null;
}
}
and here is where i create the event listener.
$(timer_area).on("mousedown", reposition_bar);
my html:
<div id="timer_area0" class="timer_area">
<div id="timer_bar_outer0" class="timer_bar_outer"></div>
<div id="timer_bar0" class="timer_bar"></div>
</div>
and my css:
.timer_area{
position: relative;
width: 100%;
margin: 20px auto 10px auto;
height: 20px;
backgroud: #fff;
}
.timer_bar{
z-index: -1;
display: block;
width: 3%;
height: 8px;
border-radius: 4px;
clear: both;
position: absolute;
margin-top: 6px;
box-shadow: inset 0px 1px 0px 0px rgba(250,250,250,0.5),
0px 0px 3px 2px rgba(250,250,250,1);
background-color: #fff;
}
.timer_bar_outer{
padding: 0px 3% 0px 3%;
width: 100%; /*this should be same number as 100/windowduration*/
height: 20px;
display: block;
z-index: -2;
position: absolute;
background-color: rgb(0,0,0);
margin-left: -3%;
border-radius: 10px;
box-shadow: 0px 1px 0px 0px rgba(250,250,250,0.1),
inset 0px 1px 2px rgba(0, 0, 0, 0.5);
box-sizing: content-box;
}
.timer_bar.on{
background-color: blue;
box-shadow: inset 0px 1px 0px 0px rgba(250,250,250,0.5),
0px 0px 3px 2px rgba(5,242,255,1);
}
Edit after @tlindell comment:
thank you for your comment. I have tried out the range sliders but could not style them with css the way i wanted after doing much research. (ie my vertical slider worked perfect until I put a box shadow on it and it did not work vertically anymore)... I am happy with my slider. its just i was wondering if i could have written the reposition_bar method better because the way ive done it above, this code:
document.onclick = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
is exaclty the same as this accept they are different event handlers eg onmousemove and onclick:
document.onmousemove = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
so can i combine them in a way for example
document.onmousemove || document.onclick = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
Thanks for your edit @tlindell. It is something like what I would like but I tried the following which doesnt really have the desired effect. It is not registering the mouseup event.
function reposition_bar(mouse_touch_position){
document.onmousemove = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
this.onmouseup = function() {
document.onmousemove = null;
}
}
$(timer_area).on("mousedown click", reposition_bar);
I would like the function to be called with onmousedown and then within the function I would like it to handle the events of onmousemove and onclick. can I do something like this within the function reposition_bar:
function reposition_bar(mouse_touch_position){
document.on("mousemove click") = function(mouse_touch_position){
var timer_bar_position = $(timer_bar);
timer_bar_offset = timer_bar_position.offset();
var total_width_timer = $("#timer_bar_outer0").width();
var new_width_timer = (((mouse_touch_position.pageX - timer_bar_offset.left)/total_width_timer) * 100); /*converting to percantages because the width of the timer is in percentages in css*/
player.currentTime = (window.duration)*(new_width_timer/100);
}
this.onmouseup = function() {
document.onmousemove = null;
}
}
$(timer_area).on("mousedown", reposition_bar);
That does not work at all though so I guess the syntax is wrong in this line within the function:
document.on("mousemove click") = function(mouse_touch_position){
}
Thanks again. I am quite new to this :)
Thanks @tlindell for the answer. This is what i did in the end. (see the window.onload section for the edits)
<script>
var player;
var intv;
var duration;
var song_id;
var button;
//init
window.onload = function(){
player = document.getElementById('audio_player');
$('#volume_control_area').on('mousedown mouseup mouseleave click', function(e){
if(e.type === 'mousedown'){
$(this).bind('mousemove', reposition);
}
else if((e.type === 'mouseup') || (e.type === 'mouseleave')) {
$(this).unbind('mousemove', reposition);
}else if(e.type === 'click'){
$(this).bind('click', reposition);
}
});
}
function reposition(mouse_volume_position){
var volume_knob_position = $(".volume_control_knob");

Welcome Jquery ui!
you can resize divs here:
jquery ui resizable
and get range sliders here:
Jquery ui silders
EDIT
absolutely! here is the way to do that.
$('#element').on('keyup keypress blur change', function() {
...
});
Or just pass the function as the parameter to normal event functions:
var myFunction = function() {
...
}
$('#element')
.keyup(myFunction)
.keypress(myFunction)
.blur(myFunction)
.change(myFunction)
