Can I make a button's text change dynamically on click?

[Stewart Eade]

I have stolen a user macro for "Expand All" from this forum, but my users have asked if it is possible to make the text in the button change based on the state of the page.

So it toggles between "Expand" or "Collapse" based on whether the button has been clicked.

This is the macro I have used, but not sure how to change to get dynamic button name:

<p align="left"><button name="toggleAll" id="toggleAll" type="button" class="aui-button" aria-pressed="false" style="background-color:blue;color:white;font-weight:bold">Expand All / Collapse All</button></p>

<script type="text/javascript">
AJS.toInit(function ()
{
AJS.$('#toggleAll').click(function()
{
var expanded = jQuery(".expand-icon.aui-iconfont-chevron-down").closest("div");
var unexpanded = jQuery(".expand-icon.aui-iconfont-chevron-right").closest("div");
if (expanded.size() > unexpanded.size()) {
expanded.each(function(){ jQuery(this).trigger("click");})
} else {
unexpanded.each(function(){ jQuery(this).trigger("click");})
}
});
});
</script>

@Stewart Eade which button in trello are you trying to change? i could probably make something with PixieBrix that changes the text of the button when its clicked, but to show an example I'd need to know which button you're talking about

Thanks for your response. I managed to work it out and the new code (shown in BOLD) below:-

<p align="left"><button name="toggleAll" id="toggleAll" type="button" class="aui-button" aria-pressed="false" style="background-color:blue;color:white;font-weight:bold">Expand All</button></p>

<script type="text/javascript">
const btn = document.getElementById("toggleAll");

AJS.toInit(function ()
{
AJS.$('#toggleAll').click(function()
{
var expanded = jQuery(".expand-icon.aui-iconfont-chevron-down").closest("div");
var unexpanded = jQuery(".expand-icon.aui-iconfont-chevron-right").closest("div");
if (expanded.size() > unexpanded.size()) {
expanded.each(function(){ jQuery(this).trigger("click");
btn.innerText = "Expand All";})
} else {
unexpanded.each(function(){ jQuery(this).trigger("click");
btn.innerText = "Collapse All";})
}
});
});
</script>
