Here is my array:
var myarray = [["d1", "sections/Dashboard-summary.html", "Dashboard"],
["add", null, ""],
["20", "sections/MW-1-summary.html", "MW-1"],
["21", "sections/SB-5-summary.html", "SB-5"]]
How do I remove the second element ["add", null, ""]
so that the new array is
[["d1", "sections/Dashboard-summary.html?781", "Dashboard"],
["20", "sections/MW-1-summary.html?903", "MW-1"],
["21", "sections/SB-5-summary.html?539", "SB-5"]]
That element might not always be in the second position but its first value will always be "add". How do I remove the array with the first value (myarray[1][0])
of "add"?

Use a loop with splice()
.
for (var i = 0, myarrayLength = myarray.length; i < myarrayLength; i++) {
if (myarray[i][0] === 'add') {
myarray.splice(i, 1);
break;
}
}
jsFiddle .
You can remove it completely (slow):
myarray.splice(1, 1);
You can delete it from the array, and left a "hole" in it (left the position 1 undefined):
delete myarray[1];
