Basically what I have for this code is I want to take the number of pets a user inputs, take down the names of the pets, and put them in a variable that I can print out later in the program.
{
return document.getElementById(id);
}
var processInfo = function ()
{
//Setting varibles from HTML
first = $('firstname');
last = $('lastname');
petnum = $('numpets');
//For loop for pet names
var Petlist = '';
for (cntr = 1; cntr <= petnum.value; cntr++)
{
petID = 'pet' + cntr;
PetName = $(petID).value;
Petlist += PetName;
}
//Checking for blank strings to be filled
/*var errorFoundFlag = 'N';
if (something is found to have an error)
{
msg += "error found with something";
errorFoundFlag = 'Y';
}
if (somethingElse is found to have an error)
{
msg += "error found with somethingElse ";
errorFoundFlag = 'Y';
}
if (errorFoundFlag == 'N')
{
Do the processing called for in the "Success" section above
}
*/
$("msg").innerHTML = Petlist;
}
window.onload = function ()
{
$("mybutton").onclick = processInfo;
}
<p>How Many Pets do you have? (0-3): <input type="text" id="numpets" size="1" maxlength="1">
<span id="numpets_error"></span>
</p>
<p>List your Pet's names:
<input type="text" id="pet1">
<input type="text" id="pet2">
<input type="text" id="pet3">
</p>
<p><input id="mybutton" type="button" value="Submit Information"></p>
<p id="message"></p>
I want the for loop to take ids="pet1" "pet2" and "pet3" and put them together as a string into a variable called Petlist
. I want to set inner.HTML
to petlist
, but I am getting the following error:
Uncaught TypeError: Cannot set property 'innerHTML' of null on line 43
where I call $("msg").innerHTML = Petlist
What am I doing wrong?
You are combining DOM
with jQuery
. That won't work.
Use the html
method which is the jQuery
equivalent of innerHTML
.
$("msg").html(Petlist);
