Is it possible to get the target (final) calculated css property value during a css3 transition in Javascript?
I found this answer: Is it possible to get the target css property value during a css3 transition in Javascript?
So, I can get it as
document.getElementById('transition_div').style.width
BUT this works only when target css property is specified in css. I need get target property value which is calculated dynamicaly - not specified in CSS.
HTML:
<table>
<tr>
<td id="cell-1">CELL 1</td>
<td id="cell-2">CELL 2</td>
<td id="cell-3">CELL 3 some text</td>
<tr>
<table>
CSS
td {
transition: all 3s linear;
}
JS
setTimeout(function() { //let's browser draw initial state
document.getElementById("cell-1").style["min-width"] = "300px"; //resize one of cells
setTimeout(function() {
//NOW, a second later, transition is in progress
//HOW to get target width of #cell-3 ????
}, 1000);
}, 0);

You can use window.getComputedStyle . Try this:
setTimeout(function() { //let's browser draw initial state
document.getElementById("cell-1").style["min-width"] = "300px"; //resize one of cells
setTimeout(function() {
//NOW, a second later, transition is in progress
//HOW to get target width of #cell-3 ????
var cell = document.getElementById("cell-3"),
width = getComputedStyle(cell,null).getPropertyValue("width");
// computed width is 206px
}, 1000);
}, 0);
