Small Bookmarklets That Make Testing Easier.
Feb 15, 2004These are a couple little bookmarklets that make testing your pages easier.
This is for adjusting resolution.
<script>
javascript:external.AddFavorite('javascript:void(m=window.open("","m","height=30,width=150"));m.focus();m.document.write('<form><select onchange="opener.eval(this[this.selectedIndex].value)"><option value=""><option value="self.resizeTo(640,480)">640x480<option value="self.resizeTo(800,600)">800x600<option value="self.resizeTo(1024,768)">1024x768</select></form>')','Resize')
</script>
This is for running selected code. You select the code then open the bookmark. (I used it testing this post.)
<script>
javascript:window.external.AddFavorite('javascript:void(window.open("javascript:document.write(opener.document.selection.createRange().text);document.close()"))','Run Code Selected')
</script>
Turn borders on to see table layout.
<script>
javascript:window.external.AddFavorite('javascript:void(t=document.getElementsByTagName("table"));for(i=0;i<t.length;i++){void(t[i].border="1")}','Borders On')
</script>
I use them regularly hope they're usefull to you.
Simpler Href's Must Be Operated Sooner!
Aug 30, 2006sometimes simple href:
Code:
<a href="javascript:history.back(1)">Back</a>
or
<a href="index.jsp">Home</a>
takes an almost long, about 5 seconds for loading or even so, to operate.
Could you tell me of the reason and also of possible different suggestions.
Easier Type Handling
Sep 9, 2007a common task when writing multi-use functions, is deciphering the type of data passed to the function.
Javascript's built-in data identification methods complicate function writing, by imposing a "20 questions" style interogation to determine the actual, useful to a programmer, type.
they also slow down functions, requiring both a function execution and a comparision operation upon every type guess.
a common method is something like:
if(typeof x=='string'){ };
but this has several limitations. for example:
x=[1,2,3];
typeof x; //returns 'object'
safely catching an undefined is often done like:
if(typeof x != 'undefined' ){ };
my function making got a lot easier after writing these simple prototypes:
String.prototype.type="string";
Array.prototype.type="array";
Number.prototype.type="number";
Boolean.prototype.type="boolean";
Date.prototype.type="date";
Object.prototype.type="object";
RegExp.prototype.type="regexp";
Function.prototype.type="function"
if(!!window.XML)XML.prototype.type="xml";
String.prototype.isString=1;
Array.prototype.isArray=1;
Number.prototype.isNumber=1;
Boolean.prototype.isBoolean=1;
Date.prototype.isDate=1;
Object.prototype.isObject=1;
RegExp.prototype.isRegExp=1;
Function.prototype.isFunction=1;
if(!!window.XML)XML.prototype.isXML=1;
the result?
shorter simpler code.
examples:
// smarter object typin':
[1,2,3].type; //returns 'array'
//when expecting a string or array possibility:
y=x.isString?x:x.join();
//more-flexible event handling:
function doBold(elm){ //accepts element object or id string...
if(elm.isString){elm=document.getElementById(elm);}
elm.style.fontWeight="bold";
}//end doBold
// detect an undefined variable:
if( ! x.type){ alert('x is undefined')};
by tucking the protos in your script file, you get simpler, faster-executing code. (for a tiny bit of overhead)
if script length is of upmost concern (as in a bookmarklet), these smaller protos give you simpler typing: (without the speed benefits...)
Object.prototype.type=function(){return typeof this;};
//usage:
switch(x.type()){
case 'string': return x;
case 'date': return x.toLocaleString();
case 'array': return x.join('
');
default: return x.toString();
}//end switch;
//another one:
Object.prototype.isType=function(strType){return (!! typeof this === strType)};
//usage:
x=101;
x.isType('string'); //returns false
x.isType('number'); //returns true
Easier Way To Shorten The? Code
Jul 28, 2010I tried using the "For Loop" function to accomplish this but I couldn't get it to work. show me an easier way to shorten this code up
Code:
function normal()
{
var welcomelink = document.getElementById("welcomelink");[code].....
I did try to recode everything so that the link/content and sublink/content would follow a numerical sequence...e.g. link1/content1, link2/content2, link3/content3, sublink1/subcontent1, sublink2/subcontent2, sublink3/subcontent3...etc. and then use the for...loop function but again it failed on me.

When the page loads, you have to click the Start button to get the

How To Make Function Cover All Possible Radio Buttons?
Jul 23, 2005I Have to sets of Radio buttons like so:
<input type="radio" name=p1 value=1>
<input type="radio" name=p1 value=2>
<input type="radio" name=p1 value=3>
<br>
<input type="radio" name=p2 value=1>
<input type="radio" name=p2 value=2>
<input type="radio" name=p2 value=3>
then a text area and a button:
<input size=7 name=total>
<input type="button" onclick=c()>
the function checks for the radio buttons then outputs its value in text
area.
<script type="text/javascript">
function c()
{if (p1[a].checked&&p2[b].checked)
total.value=parseFloat(p1[a].value)+parseFloat(p2[b].value)
}</script>
my question is what is the possibility of giving values to a and b such as
all radio buttons can be covered, is there a way to do this without having
to output all cases with else if structure.
JQuery :: Make A JS Function Work As A Link?
Oct 17, 2010I'm new to jQuery, but learning fast, and loving the new functionality!I'm using a Flash upload component that all works fine, and once it's complete (file uploaded) it calls function.I'm running the Flash upload in a modal (nyroModal - very cool!). The link below does what I need it to do - navigate to a new page and re-size the modal:<a href="test2.aspx#blabla" class="nyroModal">Ajax Filtering Content #test</a>What I need to work out is how to make the JS function above work in the same way as this link. I know very little JS, but I think the 'class="nyroModal" needs to be part of the link in the function some how??

Loop Function Not Working - How To Make It Work
Jun 8, 2009I have a pretty simple function set up to pull XML data into my page, but there's a couple things wrong with it. I'm REALLY new to J Script and really trying my best to learn, but for some reason I'm not yet adept at googling the right results :rolleyes:At the very bottom you can see the data from the first XML entry, so it seems the function itself is working fine, but it's not looping coorectly to access all the data.Also, I want to pull it into the "shows" div of the page, but can't figure out how to put it there (seriously, I am very new with JS). The code below is not working, but the live site has it added to the body, which does show the one entry.Here's the XML function, the XML data and the HTML markup:
