Tool for converting between JSON and string back and forth? I don't want to use a framework like Prototype just for this so ideally umm, no frameworks please lol
Also on a side note, the eval function doesn't seem to be able to convert all possible JSON strings into an object for some reason. It only works for simple JSON literals.
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);
[Code]...
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I am new to Ajax and have a bit of a gap in my understanding. I have a status monitor that sets a JS function to run every second with setInterval. When the document loads, I will need to get data from the server asynchronously (I wont know the info before hand) and use that data to set id values to find them as nodes and change them later on.
The problem is as I see it, that the callback function I will use to grab the initial data is coming back via a JSON object. The callback function is done with javascript. So, how can I take the JSON data, or converted to javascript data and set my ID values when the document loads? If I change the values dynamically with the DOM, will those values be reliable enough to use as my other recurring functions find them and set their innerHTML properties?

View 2 Replies View RelatedI am having some trouble getting an email form to work correctly. I am looking to convert some text from a text area into some basic HTML so I can insert breaks then email it.
So when the user clicks submit ... the string is taken from the textarea and converts the linebreaks into <br> tags.
The problem is not replacing the text, it is finding the line breaks I have no Idea how Code:
Is there a javascript method or whatever to convert a string to one
that is valid for http transmission?
One that converts characters like " " to %20 || < to <: etc
I am after an encompassing javascript line like:-
msg = msg.replace( whatever, http_equivalent );
I have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.
Well, I need some light in this simple thing I'm trying to do. I'm
using the XMLHttpRequest to retrieve some data from a db via php
script. The result is passed to a "results" array of strings, which
contain the data from the script.
But, the data from the script, which are the content of the strings,
have html tags in it. The thing is: I'm using the DOM to append the
string result to a table already built in the page (using
create_element and appendchild).
insertO = document.getElementById("output_table");
oTR = document.createElement('tr');
oTD = document.createElement('td');
oText = document.createTextNode(Text);
oTD.appendChild(oText);
oTR.appendChild(oTD);
insertO.tBodies[0].appendChild(oTR);
The Text var would contain something like "<font color="red">this
<b>is</b> html</font>".
This way the output isn't parsed, i.e., it shows the tags.
Does anyone have an idea on how to overcome this?
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;

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.
I have a good HTML markup parsing function which uses DOM methods to create element nodes with attributes and contained text nodes. But for some reason I am having difficulty getting the event handler attribute value (which is javascript code) converted to actual source.
[Code]...
But when I click on the button in Firefox, nothing happens. Using a Javascript debugger, the trace doesn't even enter the handler code, which effectively means the event listener has no script.
So converting the code-as-string to code-as-source using the Function constructor is not working. Or else the event handler setting function or assignment is not what it should be.
I have an Adobe pdf fill-able form field that requires a distance computation using javascript. One of the values needed in the computation is in the format of a string as feet - inches (for example: 4'-10"). I need to convert this into a number to use to complete a computation. Any code snippet or ideas on how to do this.
View 3 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 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 I can convert a string to a json array.
start code:
The problem is that .css treats snip[1] as a string but I need it to handle it as a json array.
Bad: .css
Good: .css
I am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) {
//create a container for each comment
var div = $("<div>").addClass("entry round").appendTo("#characters");
//add author name and comment to container
$("<div>").addClass("details").appendTo(div);
$("<span>").addClass("main-armory button").appendTo("div.details");
}
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
<div class="details"><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span></div>
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.
Currently using: version: 2.47 (04-SEP-2010)
If I have iframe: true, my JSON response back is always:
<head></head><body>{"WEBSITE_URL":"test","ASSETTYPE_ID":0.0,"ASSET_RESULT":{"ASSET_ID":9,"ERROR":false},"ASSETTYPE":"link","NAME":"test","DESCRIPTION":"test"}</body>
Was this done for a specific reason (note the Head/Body tags)? Is there a safe way of parsing this JSON request out? Am I doing something wrong?
I am using ajax to get the followign json string from php
i show the string in javascript code...
now i want to get ID value in javascript.
I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...

I am slowly working through learning/writing a JS project.here is the core issue.:
var pt =<? echo json_encode($prt);?>
alert(pt) // for diagnostic purposes
json is flattening the PHP array to be used in the script.However, the alert shows me that I only get {[ ,which is just before the first set of double quotes.JS quits at the double quotes, leaving me with an undefined array.How do I fix this?
