in my process text filed in array i need to get the value via javascript but my code is not working my code following
<input type="text" id="itemid[]" name="itemid[]" class="span12"/>
and javascript code is
function getstock()
{
var itemidarr=document.getElementById('itemid[]');
if(itemidarr!= null)
{
alert(itemidarr.length);
}
}
any other solution for this
The IDs can't contain brackets, these: [], so:
<input type="text" id="itemid1" name="itemname1" class="span12"/>
<input type="text" id="itemid2" name="itemname1" class="span12"/>
<input type="text" id="itemid3" name="itemname1" class="span12"/>
Then you have to loop through the IDs:
function getstock()
{
for(var i=1; i<=3; i++){
var itemidarr=document.getElementById("itemid"+i);
if(itemidarr!= null) alert(itemidarr.length);
}
}
[] in the fields names are important. It lets PHP know to treat multiple elements with the same name as an array. It's strange, but that's the way it is :) php.net/manual/en/faq.html.php#faq.html.arraysThe id attribute here cannot contain [ ].
Put your textboxex in "fieldset tag" Like:
<fieldset id="field">
//Put you text boxes here<input type='text'>
</fieldset>
Access these by:
document.getElementById("list....").getElementsByTagName("input")[indexoftext];
indexoftext is the text box you wan to choose.
Hope it helps!
you can try something like this below
<input type="text" id="itemid" name="itemid" class="span12"/>
function getstock()
{
var itemidarr = document.getElementsByName('itemid');
for(var i = 0; i < itemidarr.length; i++){
var item=document.getElementsByName('itemid')[i].value;
if(item!= null)
{
alert(item);
}
}
}
[]? They are essential for processing the fields in PHP. php.net/manual/en/faq.html.php#faq.html.arraysYou can't make an array to fill in an input text, only for input like radio or checkbox.
Text input only accept a single string.
function getstock() {
var a = []; jQuery.each(this, function(i, field){ a.push($.trim(field.value)); }); return a;
}
can u use this code
i got the result
function getstock1()
{
alert("test");
var itemidarr = document.getElementsByName('itemid[]');
for (var i = 0; i < itemidarr.length; i++)
{
alert(itemidarr[i].value);
}
