I need assistance with Coffee Script to determine if an element is in an array. I am struggling with the syntax and wondering if there is a way to achieve this without having to iterate through each item individually.
Thank you,
if $(this).val() is present in ["needs_cover","comatose"]
$("#head_count").hide()
else
$("#head_count").show()
To simplify the code, you can remove the is:
if $(this).val() in ["needs_cover","comatose"]
$("#head_count").hide()
else
$("#head_count").show()
Here is the equivalent JavaScript code:
var _ref;
if ((_ref = $(this).val()) === "needs_cover" || _ref === "comatose") {
$("#head_count").hide();
} else {
$("#head_count").show();
}
When facing a typical scenario like this, you can create a function that streamlines the process and makes your code more concise, as shown below:
toggleVisibility = (valueSelector, elementSelector, comparisonArray) => {
if ($(valueSelector).val() in comparisonArray) return $(elementSelector).hide();
$(elementSelector).show();
}
I find this approach to be cleaner and easier to follow. It's just my personal preference.
To use the function, simply make a call like this:
toggleVisibility(this, '#head_count', ['needs_cover', 'comatose']);
