javascript - give all elements an ID of matched content from an array -

i need give <span> tags id of whatever content matches array1.

array1 = ["155","80","200","123"]; <span>155</span> <span>80</span> <span>200</span> <span>123</span>

the end result being:

<span id="155">155</span> <span id="80">80</span> <span id="200">200</span> <span id="123">123</span>

here best can muster:

var arr = $('span:contains(array1[i])'); (var = 0; < arr.length; i++) { arr[i].id = i; }

i neither savvy javascript or arrays. help appreciated, give thanks you.

first elements tag name span :

var s = document.getelementsbytagname('span'); var len = s.length;

now, in loop, give each element ids :

for(var i=0; i<len; i++) { var inner = s[i].innerhtml; s[i].id = inner;

this give respective ids spans.
