I have a javascript which contains something like this
var f = function(){
if(){
}else{
}
}
and I need to add ; at the end, like this
var f = function(){
if(){
}else{
}
};
I need some help to get the closing function } tag and not the } tags from inside the function.
Thanks
You can't, if all you can use is regex. It'd be very much like parsing HTML with regex.
Instead, see if you can find an AST parser for javascript in PHP - that's what you'll need to be able to find the appropriate closing bracket.

I've got a word in an HTML paragraph. For example 'string':
<p id="myWord">string</p>
I want to change only a character of that word. For example 'strong':
So I add an html button that calls a function:
<button onclick="myFunction">replace 'i'</button>
the function in JS is this but it can't access to the fourth character of myWord:
function myFunction{
document.getElementById("myWord[3]").innerHTML = 'o';
}
Here is the unWorking fiddle: https://jsfiddle.net/su3Lrezr/4/
How can I access to a index of a word in a html paragraph? I already tried to convert myWord into an array with split() method but it doesn't work.
Thanks everybody
Array method:
You'll want to split the string at value 'i' Then rejoin them together with an 'o' in the middle. Then update your innerHTML. You will need the split() function. This will work:
function myFunction(){
var word = document.getElementById('myWord').innerHTML;
var result = word.split('i');
var newword = result[0] + "o" + result[1];
document.getElementById('myWord').innerHTML = newword;
}
Also, as a commenter has mentioned your syntax for calling functions is wrong. You must call functions like this: myFunction() and declare them like this: function myFunction(){ }
I want to do a pretty simple thing, a function that does a query to mongoDB using a Like. But I don't seem to make it works.
At the moment it looks like this :
searchChannel(valueToSearch:string){
this.items = Channels.find({'title':'/' + valueToSearch + '/'});
}
I tried /valueToSearch/ too, but it doesn't return any result.
To construct a regular expression from string you can use RegExp
searchChannel(valueToSearch:string){
this.items = Channels.find({'title': new RegExp(valueToSearch)});
}
Ok so... the issue is likely because you're inserting / characters into your mongo query. I think you want something like this:
searchChannel(valueToSearch:string){
this.items = Channels.find({'title': valueToSearch });
}
Unless the / characters are part of your stored content, they shouldn't be added to your search string.
I have a publication, essentially what's below:
Meteor.publish('entity-filings', function publishFunction(cik, queryArray, limit) {
if (!cik || !filingsArray)
console.error('PUBLICATION PROBLEM');
var limit = 40;
var entityFilingsSelector = {};
if (filingsArray.indexOf('all-entity-filings') > -1)
entityFilingsSelector = {ct: 'filing',cik: cik};
else
entityFilingsSelector = {ct:'filing', cik: cik, formNumber: { $in: filingsArray} };
return SB.Content.find(entityFilingsSelector, {
limit: limit
});
});
I'm having trouble with the filingsArray part. filingsArray is an array of regexes for the Mongo $in query. I can hardcode filingsArray in the publication as [/8-K/], and that returns the correct results. But I can't get the query to work properly when I pass the array from the router. See the debugged contents of the array in the image below. The second and third images are the client/server debug contents indicating same content on both client and server, and also identical to when I hardcode the array in the query.
My question is: what am I missing? Why won't my query work, or what are some likely reasons it isn't working?
In that first screenshot, that's a string that looks like a regex literal, not an actual RegExp object. So {$in: ["/8-K/"]} will only match literally "/8-K/", which is not the same as {$in: [/8-K/]}.
Regexes are not EJSON-able objects, so you won't be able to send them over the wire as publish function arguments or method arguments or method return values. I'd recommend sending a string, then inside the publish function, use new RegExp(...) to construct a regex object.
If you're comfortable adding new methods on the RegExp prototype, you could try making RegExp an EJSON-able type, by putting this in your server and client code:
RegExp.prototype.toJSONValue = function () {
return this.source;
};
RegExp.prototype.typeName = function () {
return "regex";
}
EJSON.addType("regex", function (str) {
return new RegExp(str);
});
After doing this, you should be able to use regexes as publish function arguments, method arguments and method return values. See this meteorpad.
/8-K/.. that's a weird regex. Try /8\-K/.
A minus (-) sign is a range indicator and usually used inside square brackets. The reason why it's weird because how could you even calculate a range between 8 and K? If you do not escape that, it probably wouldn't be used to match anything (thus your query would not work). Sometimes, it does work though. Better safe than never.
/8\-K/ matches the string "8-K" anywhere once.. which I assume you are trying to do.
Also it would help if you would ensure your publication would always return something.. here's a good area where you could fail:
if (!cik || !filingsArray)
console.error('PUBLICATION PROBLEM');
If those parameters aren't filled, console.log is probably not the best way to handle it. A better way:
if (!cik || !filingsArray) {
throw "entity-filings: Publication problem.";
return false;
} else {
// .. the rest of your publication
}
This makes sure that the client does not wait unnecessarily long for publications statuses as you have successfully ensured that in any (input) case you returned either false or a Cursor and nothing in between (like surprise undefineds, unfilled Cursors, other garbage data.
I really love the autofromat feature. I makes your code more readable and in case of JavaScript tells you, when there are synatcs errors (missing brackets etc.).
However sometimes the formatting makes the code harder to read. e.g. when it puts a long array inizalisation into a single line. In that case I don't want him to format it, but rather leave it ofer multiple lines.
E.g.
define([
'jquery',
'aloha',
'aloha/plugin',
'ui/ui',
'ui/scopes',
'ui/button',
'ui/toggleButton',
'ui/port-helper-attribute-field',
'ui/text'
// 'css!youtube/css/youtube.css'
],
function(
$,
Aloha,
Plugin,
Ui,
Scopes,
Button,
ToggleButton,
AttributeField)
{
this array should stay like this and don't become this:
define(['jquery', 'aloha', 'aloha/plugin', 'ui/ui', 'ui/scopes', 'ui/button', 'ui/toggleButton', 'ui/port-helper-attribute-field', 'ui/text' ], function($, Aloha, Plugin, Ui, Scopes, Button, ToggleButton, AttributeField) {
Is there a special tag, to tell eclipse not to format the code?
OK, it took me some time to find the right setting so I will post a toturial here.
Go to Window Preferences and Search the Formatter you are using. In my case it was under 'Aptana Studia' -> 'Formatter'. (Depending on your Package this differs, e.g. the Java Formatter is under 'Java' -> 'Code Style' -> 'Formater').
Noww create a new Build profile since you can't override the old one.
Now enable the Formatter tags.
Now you can use the
- #formatter:on
- #formatter:off
tags to disable code formatting.
Example:
this code:
function hello() { return 'hello';
}
//#formatter:off
/*
|\ _,,,---,,_
/,`.-'`' -. ;-;;,_
|,4- ) )-,_..;\ ( `'-'
'---''(_/--' `-'\_) fL
*/
//#formatter:on
function
world() {
return 'world';
}
Will get formatted to like this
function hello() {
return 'hello';
}
//#formatter:off
/*
|\ _,,,---,,_
/,`.-'`' -. ;-;;,_
|,4- ) )-,_..;\ ( `'-'
'---''(_/--' `-'\_) fL
*/
//#formatter:on
function world() {
return 'world';
}
Note how the function definition is formatted correct, while the ascii art isn't

Try to make an empty comment after each line:

Not nice, but I think it will work.
i know how i get the current URL with typoscript, but i dont know how i can parse this url into a variable so i can use and work with it.
temp.getUrl = TEXT
temp.getUrl.typolink {
parameter.data=TSFE:id
returnLast=url
}
This example returns me an url segment like 'This/is/just/a/test.html', so long – perfect!
Now i try to save this url into an Variable like
temp.getUrl = TEXT
temp.getUrl.typolink {
parameter.data=TSFE:id
returnLast=url
}
wiredMindsCompleteUrl < temp.getUrl
This results everytime just with 'TEXT' :( i kinda depressed.
Please help :)
The question is, where do you want to use it.
If you want to use it in different places in TypoScript you can f.e. render it into stdWrap.append / stdWrap.prepend of your links.
myMenu = HMENU
myMenu ...
myMenu.stdWrap.append < temp.getUrl
You could just put it into an Register:
page.1.LOAD_REGISTER
page.1.getUrl < temp.getUrl
and f.e. use your register in the tilte-Tag of an image:
lib.MyImage = IMAGE
lib.MyImage.file = ...
lib.MyImage.titleText.data = REGISTER:getUrl
lib.MyImage.tilteText.noTrimWrap = | makes no sense (IMHO:) ||
If you need it in your extension, just use it with cObjGetSingle.
plugin.tx_yourextension_pi1.getUrl < temp.getUrl
Inside your extension use it via
function main($content, $conf) {
$this->conf = $conf;
return $this->cObj->cObjGetSingle($this->conf['getUrl'], $this->conf['getUrl.'], 'getUrl');
}
Side note: use lib.getUrl instead of temp.getUrl, otherwise you can get in trouble with non-cached TypoScript parts.
