jQuery equivalent to “getElementsByName”

Question

What is the correct jquery syntax for a getElementsByName call?

Here is my javascript code:

var test = document.getElementsByName(tableN         


        

Answer 1

"[name=tableName]" is bad syntax in 2 ways. First, you should put your name in quotes, so it should be "[name='tableName']" and second, in the first case, you're using a variable and in the second, a string, so in reality it shoudl be "[name='" + tableName + "']"

good call also on the fact that you have an index on your getelementsbyname() call, if you select item [0] then it will only return one item.

Answer 2

Interesting to know that jquery is a LOT slower than the native method here. See the jsPrefs test : http://jsperf.com/getelementsbyname-vs-jquery-selektor/4

Answer 3

Remove the index from the first statement

These are equal.

var test = document.getElementsByName(tableName);
var test = $("[name=tableName]");

Answer 4

Use quotes around the attribute selector:

$('[name="somenamehere"]');

If you need to use a variable within a selector, you need to use string concatenation to get the value of the variable:

$('[name="' + tableName + '"]');

---

Typically one should avoid using the [name] attribute in favor of the [id] attribute, because selection would be simpler as:

$('#someidhere');
-or-
$('#' + tableID);

Answer 5

if you want to get a element value use this code:

var test1 = $("[name='tableName']").val();
alert(test1);

These are equal to get value of specific index[]:

For same index [0]

var test2 = $("[name='arryname[]']")[0];
alert(test2.value);

var test3 = $("[name='arryname[]']").get([0]);
alert(test3.value);
