Since we are nominated for a sharing award...
Here is our options form not letting students pick the same subject more than once
2021-02-16 14-37-29.mp4
And here is the code that does it:
<style>
a.disabled {
pointer-events: none;
cursor: default;
background-color:#999 !important;
}
</style>
<script>
var $form;
var that = this;
var values = [];
setTimeout(function() {
var $site = that.element.closest(".sites-site-content");
$form = $site.find("div[data-name='Widget.Forms']");
$form.off("select");
$form.off("input[type=radio]");
$form.on("change", "select", function() {
addAlltoArr();
checkArr();
});
$form.on("change", "input[type=radio]", function() {
addAlltoArr();
checkArr();
});
}, 2000);
function addAlltoArr() {
values = [];
$form.find("select").each(function() {
if (this.value != "") {
values.push(this.value);
}
});
var selected = $form.find("input[type='radio']:checked");
if (selected.length > 0) {
selected.each(function() {
values.push($(this).val());
});
}
}
function checkArr() {
if (hasDuplicates(values)) {
alert("You have chosen the same subject twice.\nYou will not be able to save your choices until you fix this.")
$form.find("#submit_form").addClass("disabled");
} else {
$form.find("#submit_form").removeClass("disabled");
}
}
function hasDuplicates(array) {
var valuesSoFar = Object.create(null);
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (value in valuesSoFar) {
return true;
}
valuesSoFar[value] = true;
}
return false;
}
</script>
Hi @johnmorris01
This little widget should do what you want....
Instructions for set up
1. create a new site and drag a html widget onto the page
2. copy and paste the attached code, then save the site.email.html
Instructions for use
1. Search for a class in the first box. Just type a few letters of the class name and a list to choose from should appear
2. Select a class and the member of that class will appear - all will be selected by default
3. Un-select any students you do not want to email by clicking on them
4, Press the "copy" button and the email address list will be copied to your clipboard. A member of staff would then need to open a new gmail message and paste (or ctrl+p) the address list into the send to field.
If clipboard access is not supported by the browser, a box will appear containing the email address list. This can be copied in the more conventional way and then pasted later.
Hope it helps!
Paul
