here is my code
function ()({var dob=/\s*\d*\s*\.?\s*\d*\s*-\s*\d*\s*\.?\s*\d*\s*/;
var x=prompt("Enter data","");if (x.test(dob)){var y=x.split("-");
alert(parseFloat(y[0]));
alert(parseFloat(y[1]));}
else{alert("Not Matched");}})();
it takes input range as a-b(example 4-5) and splits its value to a and b.if a single decimal is entered it shows Not Matched.It works fine in Jsfiddle but not working in chrome as bookmarklet.Please help
Looks like the problem is with your regex test.
Instead of this:
x.test(dob)
Try this:
dob.test(x)
Edit: Also, you're missing the beginning opening parenthesis '(' before the function.

I have an extremely simple example here: http://jsfiddle.net/daylight/hqHSr/
To try it, just go to the fiddle and click the [Add Item] button to add some rows.
Next, click the check box next to any item and you'll see something similar to the following:
Problem: Only Displays Numeric Part
The problem is that the value should display the entire string shown in the row. In the example that means it should display: 86884-LLMUL.
Notice that it only displays the numeric part of the value.
If you look at the control you'll see that I'm using an input of type="text".
Also, if you look at the model (simpleItem) object you'll see that the one property it has is a string.
The JavaScript for the model class looks like:
function simpleItem(id) {
this.id = id;
}
My Attempt To Force to String Type
When I generate each of the simpleItems I even go so far as to set them to a character when I call the constructor (just to force the id to be set to a string type).
Here's the code that initializes each of the simpleItem ids:
currentItem.id = getRandom(100000).toString() + "-" + getRandomLetters(5).toUpperCase();
You can see the rest of the code in the fiddle, but the thing is I generate a random value and concatenate the value together with a hyphen and 5 letters. It's just a silly little piece of code for this sample.
But now, here is the part where it gets really odd.
If I simply change the hyphen - to another character like an uppercase X I get an error each time I click on the checkbox.
Here's the changed code and the new output, which you can see at the revised fiddle: fiddle version 2
currentItem.id = getRandom(100000).toString() + "X" + getRandomLetters(5).toUpperCase();
Also, now if you open Dev Tools in your browser you'll see in the console that Angular is now reporting an error each time you click the [Add Item] button. It looks like:
Adding Single-quotes ?Fixes? It
If you go up to the HTML and alter the following line from this:
ng-init="itemId ={{l.id.toString()}}"
to this
ng-init="itemId ='{{l.id.toString()}}'"
Now when you run it, the error will go away and it will work as you can see at the updated fiddle here: fiddle Version 3
Angular : Converts Hyphen to Minus Sign?
You see, Angular seems to be converting it to a numeric, attempting to do math on it (parsing the hyphen as a minus sign) and then truncating the string portion. That all seems to work when I use a hyphen, but when I use a X then Angular chokes.
Here's what it looks like when you add the single-quotes - of course the angular errors in Dev Tools console go away too.
Angular Forces to Numeric Type?
Why would this occur in Angular? It's as if it is attempting to force my string value to a numeric even though the INPUT element is type text and the JavaScript var is type string.
Anyone have ideas about this?
What About the Asterisk (multiplication symbol)?
Right as I was completing this I wondered what would happen if I changed the - to a * and ran it again. This time I saw the error below, which is indicative that something is attempting to convert to numeric.
This is the expected behavior. Angular is merely interpolating the text you have in your scope into the ng-init expression using scope.$eval and then executing that expression. This has very little to do with what is the type of the input box of the rest of the surrounding context.
It is definitely not desirable that Angular should wrap any interpolation it does in quotes, it'll break its use in all other places such as class="my-class {{dynamic-class}}".
Replace your ng-init with
ng-init="itemId =l.id.toString()"
In following with the docs, you should only use init in special circumstances anyway, you should rely on your controller for this. http://docs.angularjs.org/api/ng.directive:ngInit
I think we're just getting confused with Angular's weirdness. Basically, you're giving angular a string which it's turning into a javascript expression because it's in a {{}}. It's already, explicitly, a string (between the double-quotes):
ng-init="itemId ={{l.id.toString()}}"
It's apparently ignoring the fact that you're saying "hey, no really, this is a real string" with your l.id.toString(). It doesn't care. It's already a string and is going to evaluate it.
Just use the single quotes?
If you ng-init itemId={{undefined===undefined}}, what would you expect to happen? (it prints "true" in the alert).
Same with this: (undefined === undefined is in quotes) ng-init itemId={{'undefined===undefined'}}; prints true in the alert.
ng-init expects an angular expression. You don't have to use curly brackets there. You can simply write it like this:
ng-init="itemId=l.id" ng-click="checkBoxClicked(itemId)"
I have gone crazy trying to resolve this issue.
In my javascript code I have am defining a string variable in which I am putting an HTML table in the form of string.. i.e.:
var tData="<table><tbody><tr><a><th>Type</th><th>Score</th><th>Percentile</th></a></tr><tr><td><a>Overall</a></td><td>2.4</td><td>50%</td></tr><tr><td><a>Best 100</a></td><td>2.3</td><td>70%</td></tr></tbody></table>";
Now this variable assignment through the string is being read by my browser (both chrome and firefox) as an HTML code with line breaks. Take a look at the image below for more clarity.
The code works fine if I remove html tags and write a simple string. So I can assure you there are no previous inverted comma errors (i checked them multiple times) and no bogus characters.
I have spent too many hours on this issue. Please please help me on this.
EDIT
Added Wordpress in title and Tags as this is a wordpress issue.
Since your document is XHTML, you have to enclose your code into a CDATA section:
<script>
<![CDATA[
// code here
]]>
</script>
This prevents the browser from interpreting <...> sequences in the content as tags.
If you want multiline strings in JavaScript, you have to unescape the newline, ie
var str = "abc\
de";
Ok. Eureka!!!
I found a get around. I broke the following string :
var tData="<table><tbody><tr><a><th>Type</th><th>Score</th><th>Percentile</th></a></tr><tr><td><a>Overall</a></td><td>2.4</td><td>50%</td></tr><tr><td><a>Best 100</a></td><td>2.3</td><td>70%</td></tr></tbody></table>";
into
var tData = "<tab"+"le><tb"+"ody><t"+"r><a><t"+"h>Type</t"+"h><t"+"h>Score</t"+"h><t"+"h>Percentile</t"+"h></a></t"+"r><t"+"r><t"+"d><a>Overall</a></t"+"d><t"+"d>2.4</t"+"d><t"+"d>50%</t"+"d></t"+"r><t"+"r><t"+"d><a>Best 100</a></t"+"d><t"+"d>2.3</t"+"d><t"+"d>70%</t"+"d></t"+"r></tbo"+"dy></ta"+"ble>";
to fool the browser. I am still hoping for a better answer please.
Delete all invisible characters (whitespace) around that area,
then give it another try.
Try this:
var tData="<table><tbody>";
tData+="<tr><th><a>Type</a></th><th>Score</th><th>Percentile</th></tr>";
tData+="<tr><td><a>Overall</a></td><td>2.4</td><td>50%</td></tr>";
tData+="<tr><td><a>Best 100</a></td><td>2.3</td><td>70%</td></tr>";
tData+="</tbody></table>";

Is it possible to display characters like <, >, ', etc in Javascript's pop up alert() or confirm()?
< is automatically changed to <
etc.
The same still occurs if I change the symbols to their unicode like < to \u003c etc.
This will work for you: \< or
\\>
Maybe its a browser problem / your code (ie how you are setting the string to be displayed) because it works fine for me - what browser are you using ?
http://jsfiddle.net/manseuk/uyMhJ/1/
You could directly use alert("<") to display <. If not:
the alert function has been over written, you could use alert(alert) to display the define.
there is a bug in your browser.
Put your alert(); to external .js file. It should work fine.
I am reading a file with xmlHttp object and splitting the responseText with newlines by split method.
But "\n" character literally doesn't work. It acts like an error in my code and causes my code not even function.
Here is the line:
var lines=myPlaylist.responseText.split("\n");
There is no error if I split the array myPlaylist with other characters.
Just \n causes problem which I fail to understand.
At first, I thought the error was due to white-space:nowrap since I execute my code on Chrome.
Though I never used white-space in anywhere, I tried to set it to normal but it didn't work.
Similarly, I tried my code on other browsers (Firefox, IE etc), it didn't work either. Looks like I have a problem with using \n. Is there any other way to use newline or error with my code?
And by the way, error seems to be a syntax error since it does not just ignore \n character. Simply causes my code not to work
EDIT: An example responseText
[playlist]
File1=http://localhost:7000/Videos/Big%20Buck%20Bunny%20Trailer.ogv
Title1=Bunny Trailer
Length1=23
File2=http://localhost:7000/Videos/Dizzy%20Cat%20Video.ogv
Title2=Kedi
Length2=33
NumberOfEntries=2
Version=2
I found my own solution to my problem.
After using random special characters, \r character used for carriage return worked like a charm for my problem.
It acted like a newline \n character or at least it did its job in my case.
Thanks everyone for answers and helpful comments.
Try using this line
/\n/
Instead of this one
"\n"
Here's an SO thread that will provide a bit more insight
JavaScript string newline character?
EDIT1:
I just tested this and it splits appropriately on new lines. Can you post some of what you're trying to split?
<html>
<script>
function testSplit(value)
{
var lines = value.split(/\n/);
alert(lines);
}
</script>
<body>
<textarea id="test" name="test" onblur="testSplit(this.value);">
</textarea>
</body>
</html>
EDIT2:
Can you try converting your responseText to an object and seeing what you get from it - sorry, just shooting from the hip here since I haven't had time to mock up anything for testing.
eval("var playlistResponse = ("+ myPlaylist.responseText +")");
Here's a somewhat old article that might be useful to you: http://www.peachpit.com/articles/article.aspx?p=443580&seqNum=4
Use \\n instead of \n i tried on my code and it is working fine
This should work without problem.
Are you certain that myPlaylist has a responseText property, and that property is a string?
What happens if you catch an eventual error?
try {
var lines = myPlaylist.responseText.split(/\n/g);
alert(lines.length);
} catch (e) {
alert(e.message);
}
I am trying to update the document.title with Javascript. This works fine, but now I want to insert the ü character into the title, which gives me a question mark at the place where the ü is supposed to be.
Here is my code (I omitted the rest of the title for clarity):
document.title = '\u2019 - \u252';
The strange thing is that the \u2019 part does work and gives me a quote, as expected. My charset is UTF-8, by the way.
What am I doing wrong here?
Do you want document.title = '\u00FC'; ? the &# and \u numbers are different in many places, or so i've found in my usages.
What's \u252? It doesn't seem to be a valid unicode escape, try \u0252?
Update: Apologies. I read it wrong. Thought you were looking for "ɒ" which is the result I get...
This worked for me on Chrome, Firefox and Safari (OSX)
document.title = '\u0252';
