JavaScript - Dynamically Populate Rich Text Editor
I'm using Kevin Roth's Cross-Browser Rich Text Editor JS component. Below is a demo.php script showing how it's created in JS.
I got it working fine but I now want to dynamically add new text to the component in my php script. I know how to setup the php part to initiate the new text load event but I can't figure out how to actually get the new text into the RTE component inside a JS function. I tried this JS function but it didn't load in the new text in: PHP Code: function pre_canned_message_click() { rte1.html = 'New string'; } In the demo.php below the RTE component is loaded the same way rte1.html = but in the JS function it doesn't work. I don't know what I'm missing here. Thanks for any help...

I just installed CK Editor on my hosting account and it appears to be working fine. But instead large colored fonts, I'm getting html tags only in my email. Links and emails appear to be working fine, though... So instead looking like this: Big Bold Blue. It looks like this: <p><span style='color: rgb(0, 0, 255);'><strong>Big Bold Blue.</strong></span></p> I also tried using mail() function in php, on its own, but that didn't work either. Can anyone help me out with this? I'm not very familiar with JavaScript... Thanks in advance! Hello all I am new here but this place looked great and like one of the only places where I could find the answer to my question. I have created a page which pulls search results from various sites using PHP. It displays each result in a row in a table upon running. I wanted to add a button saying "More information" at which point, a div would appear and load the associated link for that search result within an iframe within the newly appeared div. I've been able to get a div appear and disappear on button click but, I couldn't get it to dynamically load an iframe on click with the associated search results link. Any suggestions are greatly appreciated. Also let me know if you need more information before assisting. Thanks! I assumed this is a javascript based text editor because when I turn off javascript it doesn't work. I was wondering how something like this is created. maybe not this exact one, but how would I create something like it. Maybe just a simple editor that changes text size and color.
I have a table where when the cursor passes/hovers over a cell, the current cell, as well as the top cell in its column and the first cell in its row change backgroundColor. I have text fields outside the table which I want to populate with the contents of the cells affected by the mouseover event. So as the mouse moves over different cells, the contents of the text fields changes accordingly. I've got the backgroundColor to change, but when I try to assign the contents of the cells to the text fields, nothing happens. The change of backgroundColor even stops working. This is the code I'm usign to populate the fields. Code: document.getElementById("tableID").textfieldID.value = Col1Cell[0].innerHTML;
document.getElementById("tableID").textfieldID.value = HeaderCell[n].innerHTML;
document.getElementById("tableID").textfieldID.value = this.innerHTML;
I'm traversing through the <th> and <td> tags to find the header cell HeaderCell[n] and first column cell Col1Cell[0] associated with the current cell. If I leave out these lines the backgroundColor changes, if I use them, nothing happens at all. Can't figure out why. Any suggestions? I would like to have a Javascript WYSIWYG text editor for the site mentioned on the bottom of this post. I don't need anything complex, but basic rich text editing. I know a few of them like CKEditor, TinyCME, WMD etc. I would like to hear others' experience in the regard. Thanks. Uhm, hi. So, sorry if this is the wrong place, but I hope someone can help. I'm 13 years old, and I'm slowly learning how to code. I made this website for my teacher from scratch using basic HTML tables, with a few PHP include lines I copied from somewhere. Not bad, right? Well, here's the tricky part. When she was using her previous website, she kept messing up her various widgets when she added site content (because Wikispaces sucks ) So, my hope was to create an inline editor (AJAX??) for her to only be able to edit a certain part of the page. A) ONLY SHE SHOULD BE ABLE TO EDIT IT, so I need some kind of a login system. I have access to phpMyAdmin to run MySQL queries and such. B) I was hoping for a top corner login button like Twitter, or the example shown here. C) I know I can give her access to my FTP and make a separate file, and use an include script, but she wouldn't know how to use an FTP. D) I'd prefer if the editor DID NOT use HTML. Reason being, I wouldn't want to have to make her use <br> every time she wants a line break. E) It should be like this. If her username is detected as logged in, a button should be displayed above the editable area that says "Edit". Then, when she clicks that, a text box shows up, she edits her text, and clicks "Submit". I'm sure this would be mighty difficult to do, but I'd much appreciate the help. I know I used phrases such as "MySQL queries" and "PHP include script", but please talk to me as if I were 4 years old. I have extremely limited coding knowledge. Also, please don't get annoyed if I ask a lot of stupid questions. Be sure to let me know if you need any more information! THANK YOU SO MUCH! ~Kyle$calise Hi Experts, i'am able create dynamically 2 text boxes ( start date & End Date) . Also i am able to create dynamically (img) calendar gif pictures beside each textbox.

I want to dynamically add a set of fields to a table when when the user onBlur the selection drop-down. I want the cursor to be in the text field of the newly added set. I have been playing around with onfocus function on the hyperlink to see if when focus is gained, it would throw the user into the text field. I am getting the impress that the field has not been created yet, so the getElementbById function cannot find the object just recently created.

Thanks jlimited Is it possible to dynamically change the value of text on a page as the user types into a text box? E.g. like: You Are Typing: <script> var keyword = document.getElementById('string'); document.write(keyword); </script> Or I could probably insert it into a function and loop it over and over again or is there a better way? Hi Guys, I am new to this forum,based on the combobox value,I am creating a textboxes dynamically in jsp .Based on the count of textboxe's the textarea content comes with <value1> like this... Here i tried like this, <html> <head> <script> function copy_data(val,id,textareaValue){ var enteredText = val; alert("enteredText -----------"+enteredText); var boxId= id; alert("boxId-----------"+boxId); var textValue= textareaValue; alert("textValue-----------"+textValue); var beforeBrac = textValue.substring(0,textValue.indexOf("<")); alert("beforeBrac -----------"+beforeBrac ); var inbracket = textValue.substring(beforeBrac.length+1,textValue.indexOf(">")); alert("inbracket -----------"+inbracket); if(boxId = "1"){ inbracket = val; } alert("inbracket -----------"+inbracket); var afterBrac = textValue.substring(textValue.indexOf(">"),textValue.length); alert("afterBrac -----------"+afterBrac ); var fstr = beforeBrac +"<"+inbracket +afterBrac ; if(boxId == "1"){ document.getElementById('txtArea').value = fstr; alert("final str value is"+fstr); } } </script> </head> <body> <input type="text" name ="a" id="1" onkeyup="copy_data(this.value,this.id,document.getElementById('txtArea').value)"/> <input type="text" name ="a" id="2" onkeyup="copy_data(this.value,this.id, document.getElementById('txtArea').value)"/> <textarea rows="2" cols="20" id="txtArea"> At W3Schools you <will> find all <the> Web-building tutorials <you> need, from basic HTML to advanced <XML>, SQL, ASP, and PHP. </textarea> </body> </html> three text boxes with some value [ value1 ] [value2] [value3 ] this is the text area content:- At W3Schools you <will> find all <the> Web-building tutorials <you> need, from basic HTML to advanced XML, SQL, ASP, and PHP. the output should be :- At W3Schools you <value1> find all <value2> Web-building tutorials <value3 > need, from basic HTML to advanced XML, SQL, ASP, and PHP... But i can't get it exactly..When i enter or delete the value it should replaced in the proper <> correctly.. If i enter the value in 1st textbox it should replace the value 1st <>.same for others also...Any Idea's ?Plz suggest me ... Hi, I am using a javascript datepicker which works fine with simple textboxes: For example: I have a textBox startDate1 in the table below: <form method="post" name="upload" action=""> <table id="tableId"> <tr> <td> <input type="text" name="startDate1" value="" readonly="true" size="10"/> <script language="JavaScript"> new tcal ({'formname': 'upload','controlname': 'startDate1'}); </script> <td> </tr> <table> </form> --Now I want to add rows dynamically to this table for which I have <a href="javascript:addRowToTable();" >Add Row</a> and the corresponding javascript function: <script type = "text/javascript"> function addRowToTable() { var tbl = document.getElementById('tableId'); var lastRow = tbl.rows.length; var iteration = lastRow; var row = tbl.insertRow(lastRow); var box = row.insertCell(0); var element = document.createElement('input'); element.setAttribute('type', 'text'); element.setAttribute('name', 'startDate' + iteration); box.appendChild(element); } </script> --This code creates the text boxes properly, but I am not being able to add the datepicker to it. Please suggest me a way to add the datepicker to the textboxes in the dynamically generated rows. Thank You Regards Rusho Shaw Hello all, I am doing a website project and in that currently I am designing a product page. I have to design add values to text boxes and drag and drop the text boxes in the workspace and delete the text boxes the user does not want and have to draw a graphical line between the text boxes which are in order. I have designed and coded everything except the graphical line part. I am a learner in javascript and Can we draw a graphical line dynamically between the text boxes in the webpage? If we can draw, can anyone let me know the tutorial for that so that I can learn and start coding as I have to submit that project soon. Thank you. I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form. For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields. php array creation: Code: if ($row_locations)
{
while ($row_locations = mysql_fetch_assoc($locations))
{
$mail[$row_locations['comp_id']]=array('mailto'=>$row_locations['mailto'], 'madd'=>$row_locations['madd'], 'madd2'=>$row_locations['madd2'], 'mcity'=>$row_locations['mcity'], 'mstate'=>$row_locations['mstate'], 'mzip'=>$row_locations['mzip'], 'billto'=>$row_locations['billto'], 'badd'=>$row_locations['badd'], 'badd2'=>$row_locations['badd2'], 'bcity'=>$row_locations['bcity'], 'bstate'=>$row_locations['bstate'], 'bzip'=>$row_locations['bzip']);
}
}
javascript function - this should create the array and send variables to text fields. Code: function updateAddress() {
var mail = $.parseJSON(<?php print json_encode(json_encode($mail)); ?>);
{
if (comp_id in mail) {
document.getElementById('mailto').value=mail.comp_id.mailto.value;
document.getElementById('madd').value=mail.comp_id.madd.value;
document.getElementById('madd2').value=mail.comp_id.madd2.value;
document.getElementById('mcity').value=mail.comp_id.mcity.value;
document.getElementById('mstate').value=mail.comp_id.mstate.value;
document.getElementById('mzip').value=mail.comp_id.mzip.value;
} else {
document.getElementById('mailto').value='';
document.getElementById('madd').value='';
document.getElementById('madd2').value='';
document.getElementById('mcity').value='';
document.getElementById('mstate').value='';
document.getElementById('mzip').value='';
}
}
}
Where is this breaking? Thanks in advance. I got a code from Javascriptkit.com found he http://www.javascriptkit.com/script/...mlticker.shtml I'm using PHP and arrays to display the HTML with a foreach loop. All that displays is the box that is supposed to have the content. Here's my PHP code: Code: $stats = array(
$txt[95] => $context['common_stats']['total_posts'],
$txt[64] => $context['common_stats']['total_topics'],
$txt[659] => $context['latest_post']['link'],
$txt[656] => $context['common_stats']['latest_member']
);
echo '<div id="myhtmlticker" class="tickerstyle">';
foreach($stats as $key => $value){
echo '<div class="messagediv"><b>', $key ,':</b> ', $value ,'</div>';
}
echo '</div>';
I've placed the javascipt code in my head area of my html. I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box. I would like to use onBlur but can't seem to get it to work. Can I do this? Help I am trying to populate a listbox using Javascript. The listbox is populated using the xml response from ajax request. Below is the code used for the same Code: var xmlDoc = xmlhttp.responseXML;
for (var i = 0; i < xmlDoc.getElementsByTagName("id").length; i++) {
traderlists.add(new Option(xmlDoc.getElementsByTagName("name")[i].childNodes[0].nodeValue, xmlDoc.getElementsByTagName("id")[i].childNodes[0].nodeValue));
}
This works fine for me. But i am facing performance issue here. some ajax requests retrieves xmls with around 11,000 nodes and this takes too much of time to populate the listbox. Can anyone please advice me with an better solution? Resolution if interested: Code: <head>
