Newline - Does Not Working After Retrieve A Record That Contains Square Symbol In The Database?
Dec 10, 2009
my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]
I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.
I am new to jquery and i have no freaking idea about jquery. One of the requirement is to use Jquery to datastore and dataretrieval so on my aspx page, a user enters a comment and clicks on "Add" button.When user clicks on Add button, I wan to add comments to database. Once data is added to db, I also want to retrieve same data, user name and current datetime as a dataset and show it on the page. How can I achieve this? I am creating a webservice which accepts "comments" as parameter and stores into database.
This code works to insert a MySQL record to a Database using AJAX. It works fine on IE, but it's not working on FF or Chrome. When I test it on FF/Chrome, i just get the text "Just a second..." and it doesn't advance from there.
I am trying to retrieved the value of the textarea with the newline preserved without having to submit the form to the server. Does anyone knows how to? I tried soft and hard wrap but both does not seems to affect the input in anyway.
Example : <form name=frm> <textarea name=ta wrap="soft"></textarea> </form> <script language=javascript> alert(document.frm.ta.value) // <-- the alerted value should look exactly as what is entered in the textbox. </script>
I am trying to create a form to edit existing data in my database. I have 2 drop down boxes( category then item) they do not work correctly. I am using php to populate the drop down boxes but there is nothing dynamic about doing this. I think I need to totally rewrite the page using java script or Ajax but I don't know what parts.So I want the user to select a category from a drop down list populated by database then have it populate the item list(so I think both of these need to be java script in case they change the category it will re populate the item list). Then I just want the selection of the item to pull the information to my form so they can update it and save the update(which I am pretty sure I can save the update as a php function but need to populate the item editable information in java script). I am really looking for help on how to setup the page with java script to make database queries and use the results to update parts of the page.In case you confused here is my flow:page loads
-User selects catagory query database for item list (on change event it think) -User selects item.Item information is pulled and displayed from database(cost, serial number, quantity(another on change event) -User is able to edit information and save updated results(run an update.php...)
I'm trying to add a single test record (a comment item) to my MySQL database.The double f:ajax tags in commandLink body are to solve a problem, where I had to double click the button to reload content div.And now here comes similar problem:After loading the page, the first click of comment adding button never works - nothing happens. I was adding some logging methods into the addComment method and it is not executed at all on first click. I suspect it's caused by my Ajax reloaded div code, because when I launch such button on a plain page, it works good.Alternatively are there other ways of realizing panel refreshing instead of using ui:include tag, which might be causing the problem here?
I have a MySQL database with a table where I store images (the file name, the mimetype of every file and the binary data in a BLOB plus a unique ID). Now what I'd like to achieve is to load an image from the database using AJAX and the POST method. Viewing a specific image using the GET method is quite simple, I just set the SRC attribute of an <img /> HTML tag to link to the PHP file and set the correct GET variables, there's no AJAX needed for that.I click a button or something, and 'behind the scenes' PHP is retrieving an image from the MySQL database, depending on the unique ID that was provided by AJAX through the POST method. AJAX uses the returned data to fill an element somewhere in the document, and that would be the freshly-loaded image.
Alright here's some code:
//PHP retrieving an image: $returnImageQuery = "SELECT imageName, mimetype, imageBinaryData FROM imageTable WHERE ID = $_POST['someID']"; $return = mysql_query($returnImageQuery );
i have a image that need user click on it and get the coordinates and store the coordinates to mysql database by using php. Here my code:
Code: <script type="text/javascript"> function(ev){ var pos=zxcPos(this.img); var mse=[ev.clientX-pos[0],ev.clientY-pos[1]]; var ary=this.ary; if (ary.length>4) [Code]...
I have an ajax script that I would like to use to retrieve a password hint from a database.Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com).All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine.
I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2?If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine?

i am currently working on aptana studio nokia wrt plugin to develop a mobile widget where i need to retrieve data from database. i've created a java servlet in eclipse to connect and execute query to the ms sql server 2005 database. in aptana, i am using js file and html file, i'm able to connect to the servlet to retrieve and process the data (split the data) into an array and display the retrieved value (array) on screen. but now i need to put the retrieved value (array) into a drop down list for selection, how could i do that?
for the drop down list, i cannot define the list, it need to be able to read from the servlet as the database is updated, it need to reflect.
I have a problem setting the default date of my jquery datepicker to the date that I retrieved from my database. I'm currently using the jquery datepicker linked to selects/ drop downs. I auto-fill my selects (month, day, year) from an external javascript. (fbDateTime.js)
I have two Javascript functions to set and retrieve a cookie: function setCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*60*1000)); var expires = "; expires="+date.toGMTString(); } else var expires = ""; document.cookie = name+"="+value+expires+"; path=/"; }
function getCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } I can set and retrieve the cookie in Internet Explorer 9. The problem is that with Chrome, I don't know if it is not setting the cookie or not retrieving it right but I always get a NULL instead of the cookie value.
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
I am trying to replace new line character with the <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
only have test one browser - Mozilla - but have the impression, that newlines when setting innerHTML doesn't go down very well with the browser. Is this sufficient for causing a hard crash or at least an exception? Can anyone verify that? (Just a guess now at the moment)
I have a form with a textarea field. I want to validate the input from the textarea using javascript. Suppose I want to check that the user has not entered the string: "Hello World!"
To do this I am using the script: form["text"].value == "Hello World"
But this gives an "unterminated string constant error" because the browser converts this to: form["text"].value == "Hello World"
