JQuery :: Live Output On Database String Length
May 28, 2011
How would I go about outputting something when a database value is being changed?
e.g. If im typing in a text field, which is saving what ive typed every time i keyup into a database field, it then shows on another page on another user computer as "User is typing something in field X"?
If no typing is happened, i.e. the database field value is not changing, nothing is echoed out.
It would also be cool to have something show "User is deleting text from field X" when the field value is getting shorter.
In pseudo code, something like if the value of database string is bigger than 100ms ago, echo out "user is typing something in", and conversly, if string is getting shorter echo out "user is deleting stuff".

Basically i have a form with jqueryui implemented (autocompletes) and I need the form to display the number of current results as the user fills the form, i.e. once the user has finishedinputtingdata into one field, the form will query the database with the current form details and return just the number of results ($mysql_num_rows)

One of the replies said I should use jquery to achieve this.

Not sure if this is the correct forum as it covers data retrieved from mysql in a .js file...
I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.

The following function takes three different fields (which combined make up a phone number) and tests it to make sure that all the characters entered are integers. If this is true, it sets form.Phone.value = entirephonenumber. I would like to incorporate an additional test which, after determining that all characters in the string are integers, checks to make sure that the string length is 10. If it is less than 10 or more, I want the entire function to return false and display an error message (the same one is fine..) Code:

i have a xml file where i do the following query:
entry_03_title=doc.documentElement.getElementsByTagName("entry")[2].getElementsByTagName("title")[0].firstChild.data;
now having the variable "entry_03_title" i would like that javascript do this:
if(entry_03_title.length>30) entry_03_title.length=6
in other words if the title is bigger than 30 chars long make it 6 chars, but this doesn't work.

Having trouble with this simple code...
if (form.SSN.length != "9") {
alert("SSN must be nine digits long");
form.SSN.focus()
return false; }
It always displays the alert even if it does equal 9 digits long. I'm new to javascript so if this is a really simple error just go with it....

i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?

This is quite mysterious. I have several list items like this:
HTML Code:
<li>Private</li>
I am looping through them all trying to get the text inside each list item for a comparison with a string from elsewhere.
Javascript Code:
var coresubmenu = document.getElementById('core').getElementsByTagName('li');for (var i = 0; i < coresubmenu.length; i++) { coresubmenu[i].onclick = function() { if (this.firstChild.nodeValue == 'Private') { // fail } alert(this.firstChild.nodeValue.length); // alerts 8 }}
IE alerts one more than the actual length in all cases. Google hasn't brought anything up for me on this one - any ideas?

When I run the following code, the .Length function returns "undefined."
var strTest = 'test';
alert(strTest.Length);
Using the typeof function, I know that JS is treating the variable as a string.

Here is the string:
Jim Peterson 21 | Ed N 31 | Mary Joe 24 | jennifer baley 22
I am trying to grab all the text other than the "|" and output that to a text field (or global variable)..
How can we do this? I can't seem to find any scripts that show me exactly how to delete all those "|"...
is there a way to put "jim peterson 21" and "ed n 31", etc.. into their own variables?

I have been searching how to connect to a database and execute some queries, and then use the data that I get to populate some tables in a web page, all this using javascript.
I am confused because I have seen in some webpages that javascript is not designed to connect with databases, and also I have see other pages where they say that it is possible.
Does anyone know if it is possible to use javascript to connect to a database (informix), and execute some procedures or queries?

I have a function that I apply to every anchor tag in a div called listnav. I do so like this:
$('.listnav a').each(function(i, el) {
$(el).click(function(ev) {
ev.preventDefault();
var href = $(this).attr('href');
[Code]....
This,among other things, causes a function called load to be called on the href of the anchor. This works fine. Howver I want to use the live() function with this as I am going to dynamically change the links in the listnav div. I tried doing it like this :
$('.listnav a').each(function(i, el) {
$(el).live('click',function(ev) {
ev.preventDefault();
[Code]....
But that does not work. My question is how would I go about changing this function so that the actions are applied to any new anchors added to the div dynamically?
