根据可变长度使文本单数或复数

Question

I am trying to make text singular or plural based on the value of templateCount . If templateCount 's value is 1 then I just want 'Template' to say that, but if templateCount is plural, I want it to say 'Templates Selected'.

What am I doing wrong with my code?

$('#templateCount').html(templateCount + " Templates Selected" + templateCount.length == 1 ? "" : "s");

Answer 1

Are you sure you thought this through? You have the string "Templates selected" there and you are conditionally appending s to the end of that (which would make it "Templates Selecteds" ).

Do this:

$('#templateCount').html(templateCount + 
    " Template" + 
    (templateCount === 1 ? "" : "s") +
    " Selected");

Answer 2

I'm not sure if what you mean is that you want to put an 's' on the end if templateCount == 1 or if templateCount's length is 1. Those can be two very different things.

If you want it based on the variable == 1, then I would try:

var templateCount;
// set it somewhere
var plural = templateCount === 1 ? "" : "s";
$('#templateCount').html(templateCount + " Template"+plural+ " Selected");

If it's the length you're actually after, change plural to

var plural = templateCount.length > 1 ? "" : "s";

Try this

 function makeStatement(templateCount) { return templateCount + " Template" + (templateCount == 1 ? "" : "s") +" Selected"; } console.log(makeStatement(1)); console.log(makeStatement(2)); 

And in your case

$('#templateCount').html(templateCount + " Template" + (templateCount == 1 ? "" : "s") + " Selected");

Answer 4

也许我读错了您的问题，但是您是否仅需要更改代码以使其看起来像这样？

$('#templateCount').html(templateCount + " Template" + (templateCount.length == 1 ? "" : "s") + " Selected");

Like this?

 var templateCount = [ 1 ]; function test() { var tmp = templateCount.length == 1 ? 1 : "Templates Selected"; $("#test").val(tmp); }
