I have read between 5 & 7 posts, have tried to play with some of the things I have read, including jQuery, but it feels as though most posts are well beyond my understanding.
I have a form which will act as a data submission tool, so let's say 100 inputs.
I just need help checking each input, and I figured that I should be able to do it using a loop.
Goal code example:
function ()
{
for (i = 1; i < 101 ; i++);
var c = document.getElementsByName("Input_row_" [i]);
if ( c = some conditionals here )
{
alert("message");
return false;
}
}
For a specific argument, one of the things I need to check is that there are no spaces in the input:
function ()
{
for (i = 1; i < 101 ; i++);
var c = document.getElementsByName("Input_row_" [i]);
if ( c = "" )
{
alert("message");
return false;
}
}
Can anyone help with my syntax or get me further towards the goal?
Thanks.

Method 1
function validate() {
for (var i = 1; i < 101 ; i++) {
var c = document.getElementsByName("Input_row_"+i)[0].value;
if (c == "" ) {
alert("Please fill in #"+(i+1));
return false;
}
}
return true;
}
Method 2
function validate(theForm) {
var elements = theForm.elements;
for (var i = 1; i < elements.length ; i++) ( // no need to know how many
if (elements[i].name.indexOf("Input_row")!=-1 && elements[i].value == "" ) {
alert("Please fill in "+elements[i].name);
return false;
}
}
return true; // allow submit
}
using <form onsubmit="return valdiate(this)"..
Without inline code:
window.onload=function() {
document.getElementById("formID").onsubmit=function() {
var elements = this.elements;
for (var i = 1; i < elements.length ; i++) ( // no need to know how many
if (elements[i].name.indexOf("Input_row")!=-1 && elements[i].value == "" ) {
alert("Please fill in "+elements[i].name);
return false;
}
}
return true; // allow submit
}
}
