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?
View 2 RepliesI 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 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]..
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?
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 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...
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 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.
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 am trying to add some HTML into a <p> element by using an AJAX request that gets a txt file with my HTML in it. That code works fine but the problem I get is that I need to enter in the path to the file dynamically. I guess I could use PHP on the server for this but I am not sure how (im not too good with PHP yet, but it is installed on my server). C# would work too as I have .NET configured as well (but again I dont know it very well).[code]I would like to replace the "linkHere" with the file path attribute I am grabbing from an XML file.I am doing that like this:$(this).attr('filePath').substr(3).replace("\","/")+$ 9this).attr('label');this works fine to make the path correctly but I need a way to inject this into the HTML/txt file to replace the "linkHere".I have an <img>with an onclick event that calls a function I made to do all this.

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 RelatedTool 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.
I have an XML file hosted by my ISP free web space. It naively treats
the file as text/plain. I would like to convert this data into a DOM
object. So far my googling has turned up nothing, although looking over
the DOM manual on Mozilla I came up with:
function convertDOM(text)
{
var lines = text.split("
");
var dom = document.createDocumentFragment();
for (var i = 0; i < lines.length; i++)
{
var node = document.createTextNode(lines[i]);
dom.appendChild(node);
}
return dom;
}
The returned object is not treated as an DOM object.
Anything I am missing / A different approach maybe?
I have an piece of html in a jquery object. When I say $(this).html I get:
<span class="value">4</span><span class="type">teaspoons</span>butter
I want to get only the piece of text from this html segment that is not in the spans. in this example, it is butter.
How do I get that?

I have an html div

Now, I want to have a button by which i can convert this <div id="myDiv"> to image or .doc....
<a href="www.mylink.com" class="myclass">click</a>
and I wanna change it to a javascript function that can be called via the SAME tag, but with this link:
[Code]...
this works to the point where it only opens the link, but now i can't figure out how to add the class to it. I tried adding it inside the body tag, but it doesn't work. So, I'm wondering if it's possible to set the class in the javascript.
I'm trying to create an onClick that will change an embedded html page. I'm using the same syntax that works for both <img> and <iframe>.
Code:
<object id="thing" data="page1.html" type="text/html">
error message
</object>
[Code]....
There must be some fundamental difference between changing an image or iframe "src" and changing an object's "data" that totally escapes me because the above script won't update/refresh/reload/change the existing embedded page (page1.html) to page2.html.
I have run the script with an "alert(document.getElementById('thing').data)" tacked onto the end of the above script, and it does, in fact, return "page2.html" in the dialogue box. So, maybe, I just need to refresh the object (without reloading the whole page!)?
I've noticed that <object> is usually used with applets and flash and sound and there seem to be commands to "run" them, but I can't find any terms to handle updating an embedded html document. Maybe there really just isn't any way to do this yet aside from iframe?
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?
how i can use it to convert an html table into a json format.

I have HTML tags stored in XML. I want to be able to use these HTML elements with Javascript, just as you can with elements in document.body. How can it be done? (And don't try and tell me I should use server-side because I have written it all for Javascript and the project is nearly complete minus this and there are practical reasons for not doing this server-side. After all, anything is possible with Javascript!)
Let me explain:
- I have HTML templates such as this [URL]
- I want javascript to populate these templates then add them to my page
- The only way I know javascript can get this kind of data is by parsing XML
- I want to parse the XML then be able to use the HTML elements just like those in document.body
- As far as I'm aware, XML is the only good way of storing data for javascript. I don't want to store it in javascript variables (too much multiline data with " and '). Nor do I want to build it using document.createElement("div")... etc
As someone not yet with any experience in computer science etc, please ignore my poor terminology! However, I'm not a beginner when it comes to javascript.
Here's the script concerned but I doubt it'll help you understand my problem: [URL]
Via ajax, data equals <h1>Special</h1>
Code JavaScript:
function searchReplaceAndDisplay(data) {
data.replace('<','<');
data.replace('>','>');
$('#modal').append(data);
}
$.get('getSpecialsHtml.aspx', searchReplaceAndDisplay);
Right now #modal displays <h1>Special</h1>, as plain text.
How can I get #modal to display 'Special' marked up as an h1 element instead of text?
