I'm trying to show/hide table rows with the help of buttons.
With the script I'm using now I'm only I'm only able to make one button and only able to show/hide one row.
I want to make more buttons where each button when pressed will show/hide a row. Also I want the button text to change between Info▼ and Info▲ as the first one does in my script.
If I have understood it correctly I should use classes instead of divs but I tried to do that without result.
If anyone could help me out with my script so I can produce more buttons where each one will show/hide a unique row when clicked on I would be grateful.
http://jsbin.com/tovicefu/1/edit This is a simple version of my layout. So when I press the first info button the row below should appear with one image.
Same with the other info button but it displays another row further below.
My script.
<script>
var button_beg = '<button class="button" onclick="showhide()">', button_end = '</button>';
var show_button = 'Info▼', hide_button = 'Info▲';
function showhide() {
var div = document.getElementById( "hide_show" );
var showhide = document.getElementById( "showhide" );
if ( div.style.display !== "none" ) {
div.style.display = "none";
button = show_button;
showhide.innerHTML = button_beg + button + button_end;
} else {
div.style.display = "block";
button = hide_button;
showhide.innerHTML = button_beg + button + button_end;
}
}
function setup_button( status ) {
if ( status == 'show' ) {
button = hide_button;
} else {
button = show_button;
}
var showhide = document.getElementById( "showhide" );
showhide.innerHTML = button_beg + button + button_end;
}
window.onload = function () {
setup_button( 'hide' );
showhide(); // if setup_button is set to 'show' comment this line
}
</script>

You can use a combination of css and javascript. In this jsBin I used a data-attribute to identify 'hideable' rows.
Css:
tr[data-hide="true"] td {
display: none;
}
Javascript to toggle visibility:
function toggleRowvisibility(e) {
var tbl = document.querySelector('table')
,rows = tbl.rows;
for (var i=0;i<rows.length; i+=1){
var hidable = rows[i].getAttribute('data-hide');
if (hidable) {
rows[i].setAttribute('data-hide', /false/i.test(hidable));
}
}
}
