In a MySQL database I have the following entry: "Fruits & Vegetables". I retrieve this to display on a webpage using PHP, convert to JSON, pass to client, process using JavaScript.
The PHP code that is passed to the client is:
Code:
$z = rawurlencode(json_encode($reqVar));
echo $z;
where $reqVar is the array of results queried from database, including one that is "Fruits & Vegetables".
When it's passed to client using AJAX, the JavaScript to process the string (decode it and then convert from JSON string to object using Prototype framework) is.
Code:
var response = decodeURIComponent(transport.responseText)
var respObj = response.evalJSON(true);
I can then display it in page. But when I pass it back to the PHP script using AJAX using the exact same process in reverse, at some point & is converted to & and if I re-enter it into the database it looks like "Fruits & Vegetables". How can i prevent this conversion? Does the order in which I convert to and from JSON and encode/decode need to be changed?
Whenever execute the following code, the URL that is formed has "?" before my name and an "=" before my value (so the URL would be "[URL]"). I need the URL formatted so that a "+" is in front of the name and a ":" (colon) to be before the value (i.e. formatted like "[URL]"). Is there a way to change this behavior? $.ajax({ url: lansaUrl('proc', 'func'), global: true, cache: false, type: "GET", data: ({"acct": object.value}), dataType: "json", success: function(result){ $("p#customerInfo").innerHTML += " "+result; }, error: function(xhr, desc, exceptionobj) { alert(xhr.responseText); }});

I have an excel doc. which is updated by many people through the day. I would like this to be converted to a web page every hour, and then saved to a directory where it can be pulled onto a website.
What I'm trying to do, I think, is to use elements of an array as a part of an object. Here's a lil' code snippet:
Code:
I'm trying to insert each of the elements of the katMusik-array into the checked-line, thus checking the checkboxes with those names. However, it doesn't seem to work.
Now I wont to edit this xml_file and again convert this xml object to in string . It seems I can change the values. But I don’t know how to convert this (Xml_file) in to string.
I have searched the web and this forum for the answer to this but am unable to find a reasonable choice. So, this is the problem I am facing.
Code: var str = "document.frames[0].document.frames[0]"; var str 1 = "document.frames[6]"; //Loop Starts { var obj1 = str + str1;
[Code]...
I know the easiest way to do this is to use eval() and it most definitely does work. The problem is that I have to use eval() inside a loop to check whether the reference is null and from what I hear, that is one of the most inefficient ways to code. I have searched for alternatives like using, var myFunc = new Function(string) and then calling myFunc(). But this does not work in my case. I cannot find any other alternative in this case. I guess one can say eval() is the only choice here but I am not too sure.
In the following example, I use the function "SetUp(SBox,AObjStr)" to send an object reference to the function "Populate(SBox,SObj)".
Seems to work OK, but it is a 2 step process to assign the JSON objects to the selected drop-down boxes. Fairly easy, but somewhat tedious, to change to fewer or more levels as desired with a common bit of code.
However, what I would like to do is simplify it a bit more ... Is there a way to bypass the "SetUp" function to "Populate" the multi-level drop downs directly? I think what I'm looking for is a way to pass a string in the function that would be recognized as an object (in this case a JSON or other form of array) and be decoded to add options to the drop-down choices, but I don't have a clue as to how that might be accomplished without the extra "SetUp" function!
Im looking to make work my script on both IE and Netscape. It works fine in IE, but netscape cant handle "dynamic" variables. I need some help!
Is there a CORRECT way to pass a string as parameter and then use it as an object in Netscape? IE does that without problem... and Netscape seems not able to handle it.. Code:
I'm a beginner in Jquery and I have a big doubt, follow at bellow the code to be better viewed: The method below is static and Static methods do not work with instance, For this reason I passed the 'nameLabel' that the typeis Label by parameter, however I need to catch the exception and show it to the user.
But I'm using Jquery and this method is used in a Ajax Request and I use the Json to pass the datas, how showed below: var idCliente= $("#<%= txtIDCliente.ClientID %>").val(); var nomeLabel = $("#<%= lblMensagem.ClientID %>"); var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }"; But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 .what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object.
after i've built an element, can i convert that element to html? the current method i'm thinking is to append this element to a new <Div> and call the Div's innerHTML but it feels rather dirty. is there a better solution?
I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code: HTML Code: var mural= new Object(); mural.top='0px'; mural.left=-'510px';
var stamps= new Object(); stamps.top='0px'; stamps.left=-'1886px'; var sprite=$(this).attr('title'); $(".image-holder").css("background-position",'sprite.top, sprite.left');
It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.
I think this is a problem converting (what is assumed to be) a string to numeric. or something like that.
rvs = s[i][j] * k; Firefox Error Console says: Uncaught exception: TypeError: Cannot convert 's[0]' to object rvs is just a (temporary, holding) variable. s is a [3][6] array on numeric values. i, j and k all happen to be zero. [Code]..
I get the "myerrorobject.filename" in the alert-Box, but I get an "undefined"-error, if I try to access myerrorobject.filename (or other properties) in the function "my_function". Why?
First, with AJAX I will get a remote web page into a string. Thus, a string will contain HTML tags and such. I will need to extract text from one <span> for which I know the ID the inner text.
Is it possible to access in this way "string variable".getElementByID() somehow?
PS: Just thinking of a proper/efficient way to extract the information from such a string. I am open to other ideas. I could load that page in IFRAME and get my access to DOM that way, yet probably it is not an eligant solution.
