I have an array in JavaScript that contains the following:
How would I go about sorting this array so that it does not appear as follows:
But as:
Any help would be great.
You need to extract the numeric values from the strings and sort based on those, just like vlood said. For example, try this code:
function mySort(arr)
{
var regex = /Value\s([0-9]+)/;
function map(str) {
return Number(regex.exec(str)[1]);
}
return arr
.sort(
function (a,b) {
var av = map(a), bv = map(b);
return av < bv ? -1 : av > bv ? 1 : 0;
})
}
mySort(["Value 1", "Value 10", "Value 11", "Value 5"]);
If you are enthusiastic about writing it yourself, you can just parse the items with an regular expression and compare the second part. Those will match something like
"Value\s[1-9][0-9]*"
you need natural sorting. i don't think there is a built-in implementation in js, but you can use some library. for example: phpjs - natcasesort
