Question

I use this code to order children from an ul. The select works fine but the value call in the error below. The li has a value.

for (var i = 0; i < $("#sortable").children("li").length; i++) {
    sortedPlayerIds[i] = $("#sortable").children("li:nth-child(" + (i + 1) + ")").val();
}

I get this error:

TypeError: (c.value || "").replace is not a function
...d*)(?:n([+\-]?\d*))?/.exec(a[2]==="even"&&"2n"||a[2]==="odd"&&"2n+1"||!/\D/.test... jquery.min.js (linje 16)

I’m using:

1.8.16/jquery-ui.min.js

1.7.1/jquery.min.js

Any idea?

Answer 1

it’s problem is in finding $(this) object in your loop, which one you get it with your counter, try this code:

$("#sortable li").each(function(){ 
     var x = $(this).text();
};
