JavaScript - How To Pass Textbox Name To Function In Javascript
I have a php script which dynamically creates a table containing text boxes with variable names. Example:
Code: echo '<td align="center" bgcolor="'.$bgcolor.'"><input type="text" name="payable_'.$key.'" id="payable_'.$key.'" value="'.$payable.'" size="3" maxlength="4" /></td> '; In the above instance the text box name might be 'payable_23323'. I need to code an onKeyUp event which sends the text box name to a function, and in that function I need to retrieve the text box name and the string after 'payable_' together with the value the user has input into the text box. Any help is greatly appreciated . . . I have been Googling this for hours to no avail - probably because I don't know what to search for . . . Thanks Similar Tutorialshi guys! i have a problem in passing the variable to function ,the variable which is used in<td> as table data.

Hello all I have a big problem I have my php like this Code: <? $codid=$_GET["cid"]; echo " <script> setTimeout(function() {CSelect();}, 100) ; </script> <div id=\"ReloadThis\"></div>"; ?> And my js funtion Code: function CSelect() { var $http, $self = arguments.callee; if (window.XMLHttpRequest) { $http = new XMLHttpRequest(); } else if (window.ActiveXObject) { try { $http = new ActiveXObject('Msxml2.XMLHTTP'); } catch(e) { $http = new ActiveXObject('Microsoft.XMLHTTP'); } } if ($http) { $http.onreadystatechange = function() { if (/4|^complete$/.test($http.readyState)) { document.getElementById('ReloadThis').innerHTML = $http.responseText; setTimeout(function(){$self();}, 10); } }; $http.open('GET', 'linii_c/select.php'+'?cod='+' PHP VARIABLE ', true); $http.send(null); } } who i can put my php variable into the funtion? Thanx in advence and sorry for my bad english! Here's something that I tested without the PHP and it worked ok. Now that I've introduced the PHP to the document it doesn't work. The PHP variable is not passing to Javascript properly. By use of some cleverly placed alert boxes, I figured out that the only thing that is getting passed forward is something called : "object HTML ImageElement" Specifically, I assign the element ID the unique ID number of the record in the SQL database. The problem isn't with the ID numbers themselves: They are alphanumeric and unique. I think it boils down to one of two lines of code. Either this isn't working (about line 12) Code: function expander(RecordID){ or perhaps it is when I am calling the function (about line 66): Code: echo "<img id='".$row['IDNumber']."' src=".$row['ImagePath']." width='5%' onMouseOver='expander(".$row['IDNumber'].");' onMouseOut='shrinker(".$row['IDNumber'].");'>";} The PHP works (I can get the images to appear, so the connection to SQL and such isn't a problem). I am sure most of the JavaScript is good, too, as I said I had it all working prior to dropping in the PHP. Since I am not going from JavaScript to PHP I don't think I need AJAX. I just need the PHP to pass to JavaScript. Any ideas?

I have completed the ajax search part of the textbox, and I am stuck with the passing value to the selectbox portion. Anyhelp will be appreciated. thanks in advance! Good day all: I want to get the value of a textbox into php without clicking the submit button. Any advice... Here is what I have My form field: Code: #1 <input type="text" style=background:transparent; border:0px; name='clientid' > This field is populated dynamically by its name with another php script in this way Code: #2 echo "formObj.clientid.value = '".toSafeString($inf["clientID"])."';\n"; Now I want to take the value in code#1 (name='clientid') and pass it to a php code that is in the same file as the form. Here is the php code PHP Code: <?php $name=$_POST['name'];//this is where the value of the text box mentioned is defined include 'datalogin.php'; error_reporting(0); error_reporting(E_ERROR | E_WARNING | E_PARSE); //test //get image details $uploaddir = "images/clientsimages/"; $get_data = "SELECT i.uploadedfile, i.clientid " .

'<br>sql : '.$get_data); if (mysql_num_rows($get_data_res) > 0) { while ($get_data_info = mysql_fetch_array($get_data_res)) { $uploadedfile = $uploaddir . $get_data_info["uploadedfile"]; } } ?> I know this may require js, but I appreciate any help! Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post"> <table> <tr> <td>Date Of Birth:</td> <td> <input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" /> <input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" /> <input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td> </tr> <tr> <td></td> <td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td> </tr> </table> </form> <script type="text/javascript" language="javascript"> <!-- document.signup.DOBmonth.value="MM"; document.signup.DOBday.value="DD"; document.signup.DOByear.value="YYYY"; function clearDOBmonth() { document.signup.DOBmonth.value="";} function clearDOBday() { document.signup.DOBday.value="";} function clearDOByear() { document.signup.DOByear.value="";} function restoreDOBmonth() { if ('document.signup.DOBmonth.value = ""') { document.signup.DOBmonth.value = "MM"; // alert(document.signup.DOBmonth.value); } } //--> </script> Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! Hello again! Is there any way to pass a function(with its parameters) to another function using a parameter? Examples: Here is how I do it now: PHP Code: function output(text){ alert(text); } function bla(text, func){ output(text); } bla("Text is here", output) //Outputs "Text is here" I only want to pass the function to bla() as a parameter. I need something like this: PHP Code: function output(text){ alert(text); } function bla(func){ output(); } bla(output("Text is here")) //Outputs "Text is here" Is this possible in some way? Thanks in advance. Hi all, I need to pass a variable to an inner function and I got it to work but: (1) I don't know why it works (2) I don't know if it's right or optimal So, please look and comment: Code: for (var h = 1.0; h <= 3.0; h += 0.5) { ed.settings.formats['spacing' + String(h.toFixed(1))] = { 'block' : 'p', 'styles' : { 'marginBottom' : String((h - 1).toFixed(1)) + 'em' } } h = (function (h) { c.onRenderMenu.add(function (c, m) { m.add({ 'title': String(h.toFixed(1)), 'caption' : 'Set the line spacing to ' + String(h.toFixed(1)), 'onclick': function () { ed.formatter.apply('spacing' + this.title); return false; } }).setDisabled(false); }); return h; })(h); }; You can ignore a lot of the code as it doesn't factor into the question... and I know that re-ordering the code can eliminate my problem (but I can't re-order it because defining the formats MUST come before "renderMenu" or else it doesn't work - and I don't want to use two loops - one to define the formats and another to define the menu). The part that's freaking me out is this: Code: h = (function (h) { c.onRenderMenu.add(function (c, m) { m.add({ 'title': String(h.toFixed(1)), 'caption' : 'Set the line spacing to ' + String(h.toFixed(1)), 'onclick': function () { ed.formatter.apply('spacing' + this.title); return false; } }).setDisabled(false); }); return h; })(h); See the strange things I have to do to get h inside of c.onRenderMenu.add()? Is this right? Can I do it any "better" or more correctly? Thanks! -- Roger Hi all I'm adding buttons to my google map through a loop. I pass some parameters, and the addButtons() function creates the buttons. How can I pass the "task" for the button to the function? In the addDomListener line below, I'm now writing the function name literally, I'd like find a way with a parameter. Thank you.. Code: // The loop... for (i=0;i<=4;i++) { oCC = addButtons(aCtrls[i],'btnContainerChild'); ... } // The function... function addButtons(cButtonID,cClassName) { var oButton = document.createElement('DIV'); oButton.className=cClassName; oButton.id=cButtonID; //... other settings here... // ===> Here, I'd like to set the click function through a parameter google.maps.event.addDomListener(oButton, 'click', function() {gmapSetCenter(defaultCenter)}); hello, only just starting using javascript, so question may not make sense but il try anyway. if i group some javascript into a function that returns false; how could i carry that 'false' out of the function so it can be used outside the function. the example below shows the validate function checks for a condition then returns false if it is met. i want this false to then be passed out of the function to then throw an error in its containing function. (goal to prevent the submitting of a form) if (checBox =="1"){ validate(); } function proceed(); function validate() { if (chilD1.value >70) { alert("Please enter your Childs correct Age"); return false; chilD1.focus(); } } i dont want the proceed function to be called, so how can the other function prevent this. Now i realise that the validate function could be incorporated into the top level function but, my form will eventually be quite large with a multiplitude of fields so i need to know how i can call back to functions and use them as objects insteasd of repeating lots of code. Hope you can help thanks.

Thanks, Dan Hey there, I'm using the service from Maxmind to get user's postal code, what I wanna do is pass the value to the next page using GET function.. I am quite new to PHP, however I think I should name the variable first and call it on the next page right? But it doesn't seem to work. Any help is much appreciated! Thanks! Basically I am trying to retrieve my image path data from mysql to my variable created in my javascript. This is the code I m using. <?php $result = mysql_query("SELECT * FROM Shop"); while($row = mysql_fetch_array($result)) { $shopName[] = $row['ShopName']; $shopLogo[] = $row['ShopLogo']; $shopDescription[] = $row['ShopDescription']; $totalShops = count($shopName); } for($i=0; $i<totalShops; $i++){ echo "<script type='text/javascript'>"; echo "var logos = new Array();" echo "</SCRIPT>"; } ?> However, I cant solve the for loop part. I wanted to pass each and every data retrieved from mysql query into the array created in javascript part inside the for loop. Can anyone teach me how to do that? Thanks. |
