Now what I do is: -use this function to create xml doc from string
[Code]...
the stirng shown at the beggining is passed to "response" (var response= xmlhttp.responseText;). Now for some reason all 3 values displayed are null... I am trying to figure why for last 2hrs but i cnt see any reason why they shouldnt be the actual values of nodes in the string...
The childNodes[0] that the script keeps editing is the text node that starts out as "test". The problem is that I want the text that I put in the table to be parsed if any markup is in it (so that a <br /> will become a break, and not literally printed out as "<br />"), something that the DOM automatically escapes. It seems a very cumbersome means of doing this is to write a javascript parser, which would go through the text and create different types of nodes as it stumbles upon markup.
I'm currently working on a pretty straight-forward AJAX application. In this application, I get some XML, and then parse it. An example of what I'm working with is as such: <?xml version="1.0"?> <postRoot xml:lang="EN"> <post type="comment" date="January 1, 1970"> <user>athlon32</user> <content>Hello World</content> </post> </postRoot>
Now, I've been able to read the XML with XMLHttpRequest , my trouble is with parsing the results. I've tried tons of things, but I just can't seem to get the different child nodes. Now, let's say we have something like this: var xml = xhr.responseXML; var allPosts = xml.getElementsByTagName('post'); Could I use childNode to access user & content? And if so, how? I've tried many things, but nothing is working :/ Is there a better way to parse the results I get back from the server?
This seems like a noob error, but I really googled it out, with not much results. Got stuck on just grabbing the XML. I validated the code with the w3.org validator and it's only missing a doctype. I've checked that the file is saved with no bom. It's served from my local Apache installation.
The error I get is:
With Firebug I got:
The jQuery code:
The headers look ok to me.Response Headers
I simplified the XML and just put it in a file, but the same error comes up even when the XML is generated with PHP. I did try to change the MIME type in the request and the response, but it's all the same.
Also, if I serve a file I get a 206, and a 200 response code for the same XML generated through PHP (using header("Content-type: text/xml")).
It should not be a cross-domain issue, as it's loaded and served from my localhost?
I did implement my script first for IE8 (sidebar gadget) without jQuery and works nicely with my PHP generated XML. Then I decided to pick up jQuery and hit the first wall head on.
I'm currently working on a web page that's acting much like a spreadsheet. There are fields that the user must fill in and then certain columns of fields add up to a sum at the bottom. I haven't been able to get it working quite right.
Here is the essence of the code Code: <form name="drillreport" method="post" action="process_report.php"> <table><tr> <td> Field 1 </td> <td> <input type="text" name="field1" id="field1" onBlur= calcTotal() /> </td> </tr><tr><td> Field 2 </td> <td> <input type="text" name="field2" id="field2" onBlur= calcTotal() /> </td> </tr><tr><td> Field 3 </td> <td> <input type="text" name="field3" id="field3" onBlur= calcTotal() /> </td> </tr><tr><td> Total </td> <td> <input type="text" name="tot_col" id="tot_col" onFocus= calcTotal() /> </td> </tr></table> ... It is more than that of course, but you get the idea.
The function I wrote is the following: Code: <script type="text/javascript"> function calcTotal() { var returned_val=0; returned_val += parseFloat(document.drillreport.field1.value); returned_val += parseFloat(document.drillreport.field2.value); returned_val += parseFloat(document.drillreport.field3.value); document.drillreport.tot_col.value = returned_val; } </script>
I use the onBlur for each of the "component fields" so that if the user changes one of the fields, it updates the total. However, I can't get this to return values properly when just field1 is entered ( NaN ) comes up. As soon as I enter the second column the total appears fine. Why wont this work if you just enter the first field?
I am really stuck in parsing a JSON string and take it's values. I got the json string as

How to Parse this and take the Results for further processing in javascript.... I am waiting to hear from you Soon..I am using jQuery for the purpose...
I have a form that I am using to generate an email with several user selected fields being part of it. As part of this form, I have a select box which allows the user to select which email addresses it should be sent to. The box works great except that the CGI script I'm sending the values to can only parse a single line for each field in the form. The issue comes into play when someone selects more than one value in the select box, the output of the select box seems to separate each value on a separate line using a line feed (or carriage return, I can't tell). The format that the CGI script needs is for a single line with each of these values separated by a comma. I'm confident that a javascript can do this fairly easily, but unfortunately, I am not very well versed in javascript. I've found a few code snippets on the web that I've mangled together, but since I don't really know what I'm doing, it isn't working out so good. I've included what I have in the form right now below (note that I've removed all of the other form data but the select box code to save space). Code:

I have scoured the internet looking for the right code but to no avail. I have gotten as far as totaling up my form but now want to format the amounts and total as currency and also want to strip out the values that =0. I have tried to use the code from other solutions (posted on the net) but I just think it is over my head because I cant figure it out. I thought I was close a few times but wasn't able to bring it on home. One of my issues is using somebody's code and not knowing where in my code to place it. [URL]
Why are anchor nodes pointing to href and text nodes pointing to [object]? As anchor and text both are objects therefore all outputs from indices 0 to 7 should be [object].
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines
var book1 = bobj1.value; var chapter1 = cobj1.value; var verse1 = vobj1.value; var book2 = bobj2.value; var chapter2 = cobj2.value; var verse2 = vobj2.value; [Code].....
I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
My code is in the attachment alex.txt.When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.
I'm trying to iterate through nodes in a Selection Range, but I'm having a bit of trouble determining why all nodes in the range aren't being hit. It seems like deeply nested nodes aren't being hit for some reason.
Here's the code I'm using.
var n = startNode; while (n) { this.visited.push('[' + n.nodeName + ']');
if (n == endNode) { break; }
if (n != startNode && n.hasChildNodes()) { n = n.firstChild; } else { while (!n.nextSibling) { n = n.parentNode; } n = n.nextSibling; } }
There doesn't seem to be any mechanism to "clear" a node of all it's children (not that its necessary very often, but I have come across situations where I'd like to clear a node of all it's children before appending other nodes). I've come up with two possibilities: Code:
I try to associate DOM nodes with other objects. Assigning custom properties to DOM nodes works in Firefox and Safari. It also works with HTML nodes in IE6. However, it appears not to work with XML nodes that are part of trees returned by XMLHttpRequest. How can I work around this limitation? For XML nodes, I need to be able to associate at most one object with each node.
The syntax I am using is node.customproperty = value
I must be missing something very obvious, but my nightly head doesn't work anymore.
Press "Insert" button to add <insnodes after each <br>. Now press "Delete" - only even <insare being removed. ins.length is reported properly, each <inshas "insert" class name. What a...?
I'm sure I'm missing something basic, but I can't seem to find what I'm looking for. If I have an xml doc where the parent node and child nodes contain elements with the same name ("name" in this case), how would I go about just getting the client's name? Here is a slimmed down version of the structure:
