I want to print or echo back code to the user, but when I attempt to I get an ILLEGAL error. How would I go about showing the below code as just normal text instead of executing it:
alert('<script>hello</script>');
I've been trying to print it to a text box with jQuery when I get the error, like so:
$('.printed-code').val('<script> write your code between these lines </script>');
If you are placing your JavaScript in a <script> element, then the </script> in the string literal will be recognised as a matching end tag for the script. Break up the string with an escape sequence (in a JS string literal, \/ means the same as /):
$('.printed-code').val('<script> write your code between these lines <\/script>');
… or keep the script in an external file and reference it with <script src="foo.js"></script>.
If you want to display information to a user, then you shouldn't be using an <input> to do so, so you will be wanting the text() method, not the val() method. (Assuming .printed-code matches a <code> element or something else that is appropriate for the task at hand).
$('code.printed-code').text('<script> write your code between these lines </script>');
You should escape the / like this: <\/script>. Otherwise you get errors, especially in old browsers where </ ends the script block (not </script>)
Someone answered earlier with an exact code example, and included a jsfiddle. He deleted the post for some reason but this was the code he provided. I would have marked that as correct. thank you all for the input
$('.printed-code').val('<scr'+'ipt> write your code between these lines </scr'+'ipt>');
The script tags are being interpreted literally.
Try:
alert('<script>hello</script>')

My issue is that CL-WHO begins each expression with a single quotation market when it turns the Lisp S-expressions into html output. This is okay most of the time, but it is an issue since I am linking my file to an external javascript file. I am trying to make this project simple, and since none of the javascript developers on my team know Common Lisp, using parenscript is likely out of the equation. Here is an example of my issue and one of the errors in my program:
:onclick "alertUser('id')"
When a particular element is pressed within the html document, this should trigger a JavaScript function called alertUser, and the id of the tag should be passed to the JavaScript function as an argument. But no matter what I do, CL-WHO will convert that string into single quotation marks, so I end up with an invalid expression. Here is what that code converts to:
onclick='alertUser('id')'>
Everything is a single quotation so 'alertUser(' is passed as the first string which is obviously invalid and I receive a syntax area in my developer tools. I thought that I could solve this problem by using the format function with escape characters. This would equate to:
CL-USER> (format t "\"alertUser('id')\"")
"alertUser('id')"
NIL
CL-USER>
But when I try that with CL-WHO:
:onclick (format nil "\"alertUser('id')\"")
That translates to:
onclick='"alertUser('locos-tacos-order')"'>
Which is also invalid html. As you can see, CL-WHO will start with a single quote no matter what. Next I tried the CL-WHO fmt function:
:onclick (fmt "\"alertUser('locos-tacos-order')\"")
When I use the fmt function it gets rid of my :onclick expression entirely when it is converted to html!:
id='id'"alertUser('id')">
Lastly I tried the str function, and got similarly invalid output to my original attempt:
onclick='"alertUser('id')"'
Obviously if I code this in pure html it will look like:
onclick="alertUser('id')">
Which is valid.
My question is simply how do I enable CL-WHO to use double quotation marks in these situations instead of single quotation marks?
#jkiiski was has the correct answer in the comments underneath my question, but I wanted to post the answer so that anyone with a similar issue in the future can resolve the problem. As #jkiiski said, there is a variable called ATTRIBUTE-QUOTE-CHAR in the cl-who package that defaults to #\'. You can simply set that variable to #\" instead in order for the default quotations used to be double quotation marks:
(setf *attribute-quote-char* #\")
After adding that line of code near the top of the file my html defaults to:
onclick="alertUser('id')"
and now the javascript can execute properly. Credit to #jkiiski for a correct answer.

Finding substring whilst ignoring HTML tags
(3 answers)
Closed 2 years ago.
I have HTML content like this:
<p>The bedding was hardly <strong>able to cover</strong> it and seemed ready to slide off any moment.</p>
Here's a complete version of the HTML.
http://collabedit.com/gkuc2
I need to search the string hardly able to cover (just an example), I want to ignore any HTML tags inside the string I'm looking for. Because in the HTML file there's HTML tags inside the string and a simple search won't find it.
The use case is: I have two versions of a file:
An HTML file with text and tags
The same file but with the raw text only (removed any tags and extra spaces)
The sub-string that I want to search (the needle) is from the text version (that doesn't contain any HTML tag) and I want to find it's position in the HTML version (the file that has tags).
What is the regular expression that would work?
Put this between each letter:
(?:<[^>]+>)*
and replace the spaces with:
(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*
Like:
h(?:<[^>]+>)*a(?:<[^>]+>)*r(?:<[^>]+>)*d(?:<[^>]+>)*l(?:<[^>]+>)*y(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*a(?:<[^>]+>)*b(?:<[^>]+>)*l(?:<[^>]+>)*e(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*t(?:<[^>]+>)*o(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*c(?:<[^>]+>)*o(?:<[^>]+>)*v(?:<[^>]+>)*e(?:<[^>]+>)*r
you only need the ones between each letter if you want to allow tags to break words, like: This is b<b>old</b>
This is it without the letter break:
hardly(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*able(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*to(?:\s*<[^>]+>\s*)*\s+(?:\s*<[^>]+>\s*)*cover
This should work for most cases. However, if the Html is malformed in which the < or > is not htmlencoded, you may run into issues. Also it may break on script blocks or other elements with CDATA sections.
Try to save the text in a variable or something, then remove all the tags and perform a normal search in that.
You can use a simple php function strip_tags().
EDIT:
So you might try to look for the first and last words (or just first and then play with the rest of the result) to locate the string, then parse the result and remove tags and check if it's the one you're looking for.
Like using regex:
hardly.cover
or even
hardly.$
And saving the location of each result.
Then use strip_tags() on the results and analyze each result if it's the one you want.
I know it's kinda weird solution but you can avoid endless regex etc.
Using JavaScript to create an xml file (for later saving in PDF). When user enters some HTML characters, like < and >, these cause problems because the program thinks they are Beginning and End HTML tags. We’ve tried the Replace function but have not found the correct Syntax yet. Any ideas?
You might try :
'<foo><bar></foo></bar>'.replace(/>/g, '<').replace(/</g, '>')
The gat the end of the regex is really important b/c otherwise it will only replace the first occurence.
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>";

I was inspecting this site in firebug. Inside the third <script/> tag in the head section of the page , I found an object variable declared in the following way ( truncated here however by me) :
var EM={
"ajaxurl":"http:\/\/ipsos.com.au\/wp-admin\/admin-ajax.php",
"bookingajaxurl":"http:\/\/ipsos.com.au\/wp-admin\/admin-ajax.php",
"locationajaxurl":"http:\/\/ipsos.com.au\/wp-admin\/admin-ajax.php?action=locations_search",
"firstDay":"1","locale":"en"};
The utility of the variable is unknown to me. What struck me is the 3 urls presented there. Why are the backward slashes present there? Couldn't it be something like :
"ajaxurl" : "http://ipsos.com.au/wp-admin/admin-ajax.php"
?
In a script element there are various character sequences (depending on the version of HTML) that will terminate the element. </script> will always do this.
<\/script> will not.
Escaping / characters will not change the meaning of the JS, but will prevent any such HTML from ending the script.
The \/\/ is to avoid the below scenario:
when the url looks something similar to "ajaxurl" : "http://google.com/search?q=</script>"
Try copy paste the url in browsers address bar. This is handled correctly. Otherwise, You might end up getting script errors and page might not work as you've expected.
imagine DOM manipulators replacing the value as it is in the src attribute of the script tag and then the javascript engine reporting multiple errors because that particular script referenced might not get loaded due to incorrectly defined src value
Hope this helps.
Life would be hectic without these lil things
It is used to escape the characters..
The backslash () can be used to insert apostrophes, new lines, quotes, and other special characters into a string.
var str = " Hello "World" !! ";
alert(str)
This won't work..
You have to escape them first
var str = " Hello \"World\" !! ";
alert(str) ; \\ This works
In terms of Javascript / and <\/ are identical inside a string. As far as HTML is concerned </ starts an end tag but <\/ does not.
