I want to use the same function for a number of fields.
<input name="taxi1" type="text" id="taxi1" size="8"
(this,1)">
function myFunction(val, itm) {
}
What can I do to get the name of the text field "taxi1"? If I try to use
[val], I'm told it is an object. I'm looking for the string "taxi1".
how would I change this to an object that I can add onto a table?
And how would I add it to the table? Code:
is there a way to get the name of the calling object of a method?
function MyFunction()
{
this.SayCallersName = _SayCallersName;
}
function _SayCallersName()
{
alert("how to get 'oTest' as output here?");
}
var oTest = new MyFunction();
oTest.SayCallersName();
What I want as an output is the name of the object I have created
without passing it to the constructor.
So I do not want oTest = new MyFunction("oTest") or something like
that. Is this possible in JScript?
reSplit is used to return an object from a string of name/value pairs.
pass reSplit()your own delimeters or use the defaults.
String.prototype.reSplit= function(d1,d2){
if(!d1) d1= /s*;s*/
if(!d2) d2= /s*=/;
var Obj= new Object, tem;
var A= this.split(d1);
var L= A.length;
for(var i= 0; i< L; i++){
if(!A[i]) continue;
tem= A[i].splat(d2);
Obj[tem[0]]=tem[1];
}
return Obj;
};
String.prototype.splat= function(delim){
var ax,L;
var d= this.match(delim);
if(!d) return this;
else{
ax= d.index;
L= d[0].length;
return [this.substring(0,ax), this.substring(ax+L), d[0]];
}
};
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.
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?
I have this string: tr= "<tr><td>test</td></tr>";
And I need to convert this string to DOM object. Like this:
var tr= document.createElement("tr");
But with the content of tr element.
Hopefully this can be done and it is easy...
I have some object like
var a = new Object();
a.name = "Title";
a.vars = new Array(6);
a.vars[0] = "4";
a.vars[1] = "22";
etc...
for about 18 objects.
If I have a string like
var str = "a";
how can I reference object data, like str.vars[0]?
I used below code to pass my xml sting.
Xml_string = <?xml version="1.0" encoding="UTF-8"?><layout>
<elements>
<i type="image" id="a18888201" [code].....
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.
Is there a way to do the following?
<script language="javascript" type="text/javascript">
function newfunction(objectName) {
// how can I create a new obect called whatever is contained in the objectName string?
}
//create a new object called myObject
newFunction("myObject");
myObject.getAttribute("objectAttribute")
</script>
I have a String formated in such as the javascript format
May I know is it posible to directly convert to var array?
Example:
But it look not work for me...
How can I do that? ( without using split function example var data = respond.split(","); )
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!
Code:
<html>
<head>
<title> Passing Object Indirectly </title>
<script type="text/javascript">

Is it possible to convert a String of date like 12/25/2005 01:00PM to a Date object?
View 14 Replies View RelatedIm 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

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.
[WebMethod]
public static string RetornaNomeCliente(string idCliente,Label nomeLabel){
string nomeCliente = String.Empty;
try {
nomeCliente = Cliente.RetornaNomeCliente(idCliente);
} catch (Exception e) {
nomeLabel.Text = e.Message.ToString();
} return nomeCliente;
}
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 = $("#<%= lblMensagem.ClientID %>");
var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }";
But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 .what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object.
View 1 Replies View Relatedafter i've built an element, can i convert that element to html? the current method i'm thinking is to append this element to a new <Div> and call the Div's innerHTML but it feels rather dirty. is there a better solution?
View 2 Replies View RelatedI have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';
var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(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.

How can I avoid type-conversion (object variable --> string) when
passing an object variable to a function?
Example:
-->
catch(myerrorobject)
alert(myerrorobject.filename);
{
my_function('bla: ',myerrorobject);
}
<---
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.
I have a very simple PHP script that returns JSON like this:
{"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this:
var url = "/test.php";
$.get(url,
function(data){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?
jQuery noob here, so I apologize in advance if this question has been asked before. My situation is this: I have a string of HTML that I've extracted from my document and passed into jQuery to manipulate as such:
Code:
var pageEl = document.getElementById("ElementId");
var contentToProcess = pageEl.innerHTML;
// pre-process contentToProcess...
var jQueryContent = $(contentToProcess);

I have a few String prototypes such as String.prototype.EscapeReg = function () { return this.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&"); }; // Escapes characters for use with a regular expressionI also have my own class/ library which is used like this var adg = new AndyG_ns.ADG_Utils(); adg.StartClock('AndyClock','dd mmm yy hh:nn'); // etc.What I would like to do is to only add the prototype to my library (not to the global namespace). The end result I'm looking for is to use code such as:
var adg = new AndyG_ns.ADG_Utils();
var myString = new adg.AString();
var parsed = myString.EscapeReg();
In addition, I want to be able to also use/create my special string sub-class within my library. I suppose I'm saying that I would like to extend or super-class the native String object.
I have JS object w/ following structure:
PHP Code:
json_data_object.422.name
thta should of out put me "hello world" as it is what it is in array but it does not as there is 422 there That's my ID from database, and I gotta use itNow, if I change that ID to something in letters say to "i" then everything is fine. ex
PHP Code:
json_data_object.i.name
That one would work, but then I have to chnge JSON string thta pulls data from DB and i cant really do that...So the question is how can I make 422 (numbers) works the same way as just string values in the array/object tree?
