Guys here a one that i found quit challenging! i have an HTML table with <tr> sections that is generated by php which looks like the following
<tr align='center' class='row_a'>
<td align='center'><input id = 'assign0' type='checkbox' name='agent_8949' value='0' /></td></tr>
<tr align='center' class='row_b'>
<td align='center'><input id = 'assign1' type='checkbox' name='agent_8950' value='1' /></td></tr>
<tr align='center' class='row_a'>
<td align='center'><input id = 'assign2' type='checkbox' name='agent_8951' value='2' /></td></tr>
<tr align='center' class='row_b'>
<td align='center'><input id = 'assign3' type='checkbox' name='agent_8952' value='3' /></td></tr>
The id's and values are generated by php, my problem is, I want to use javascript to check if anyone of the check boxes has been checked on submission meaning that i have to go through the <tr> list. here is my JS code which only works for one id.
//I know the length of the checkbox (checkBoxID) fields which is the number of rows in the database table
function validate(checkBoxID){
var ids_Prefix = 'assign';//we know all the ids starts with this string
for (var i = 0; i < checkBoxID; ++i) {
if(document.getElementById(id_Prefix+i).checked == false){//how do i check the next one????????
alert("You did not make any selection");
return false;
}
}
}
