Is there a way to conceal lengthy text within a select box and display it only when the option is selected?
I want to hide long text in a select box options, but have some sort of signal to show that more text is available. Is there a javascript solution for managing excessive text in select box options?
Take a look at this handy function:
// shortenOptions( selectElement[, maxLength] );
function shortenOptions(element, maxLength) {
var options = element.options,
option,
index;
maxLength = maxLength ? maxLength - 3 : 7;
for (index = 0; index < options.length; index += 1) {
option = options[index];
if (option.textContent.length > maxLength) {
option.textContent = option.textContent.substring(0, maxLength) + '...';
}
}
}
Simply provide a 'select' element and a maximum length when calling the function.
You have the flexibility to customize this function by incorporating logic to track selectedIndex and store values as needed.
For an enhanced experience with dropdown options, I recommend utilizing the impressive features offered by the CHOSEN jQuery Plugin. It provides excellent functionality and a wide array of customizable options to explore.
