You can write:
$(document).ready(function() {
$("#select-all-teammembers").click(function() {
var checkBoxes = $("input[name=recipients\\[\\]]");
checkBoxes.prop("checked", !checkBoxes.prop("checked"));
});
});
Before jQuery 1.6, when we only had attr() and not prop(), we used to write:
checkBoxes.attr("checked", !checkBoxes.attr("checked"));
But prop()
has better semantics than attr()
when applied to "boolean" html attributes, so it is usually preferred in this situation.
