I have a textbox and a selectbox like this:
<h3>Recipe Yield</h3>
<input style='width:100px' type="text" name="yield" class="small" />
<select name='yieldType'>
<option value='Servings'>Serving(s)</option>
<option value='Cups'>Cup(s)</option>
<option value='Loaves (Loaf)'>Loaves (Loaf)</option>
</select>
Here's a JSFiddle: http://jsfiddle.net/T3Sxb/
As you can see, the select options are in the form of word(s)
but I want to have a script where when
word
Is this possible? How can I do this? Thanks for all help!
input[type="number"]
: http://jsfiddle.net/T3Sxb/15/ I'm using data attributes so that you can declare the proper singular/plural forms for each item. Simply adding "s" doesn't work in many cases.
Also note that zero items usually (always?) takes a plural form.
HTML
<input style='width:100px' type="text" id="yield" class="small" />
<select id='yieldType'>
<option value='Servings' data-single="Serving" data-other="Servings"></option>
<option value='Cups' data-single="Cup" data-other="Cups"></option>
<option value='Loaves (Loaf)' data-single="Loaf" data-other="Loaves"></option>
</select>
JavaScript
var yield = $("#yield");
var yieldType = $("#yieldType");
function evaluate(){
var single = parseInt(yield.val(), 10) === 1;
$("option", yieldType ).each(function(){
var option = $(this);
if(single){
option.text(option.attr("data-single"));
}else{
option.text(option.attr("data-other"));
}
});
}
// whatever events you want to trigger the change should go here
yield.on("keyup", evaluate);
// evaluate onload
evaluate();
You could try this: http://jsfiddle.net/T3Sxb/7/
var plural = {
Serving: "Servings",
Cup: "Cups",
Loaf: "Loaves"
};
var singular = {
Servings: "Serving",
Cups: "Cup",
Loaves: "Loaf"
};
$( "#pluralizer" ).on( "keyup keydown change", function() {
var obj = parseInt( $( this ).val() ) === 1 ? singular : plural;
$( "#YieldType option" ).each( function() {
var html = $( this ).html();
if ( html in obj ) {
$( this ).html( obj[html] );
}
});
});
From a UX point of view, I think (s)
is perfectly acceptable. But anyway, how about this:
<option value='Servings' data-singular="Serving" data-plural="Servings">Servings</option>
then:
// you should really use IDs ;)
$('input[name="yield"]').on('change', function () {
var singular = parseInt($(this).val(), 10) === 1;
$('select[name="yieldType"]').each(function () {
if (singular) {
$(this).val($(this.attr('data-singular')));
} else {
$(this).val($(this.attr('data-plural')));
}
});
});
