(This is embarrassing, I should not be asking this...but I just don't see the problem...)
As part of a JS-Fn, I would like to give the user immediate feedback by opening a jBox-Tooltip that is attached to the control user is dealing with. But the control tip does not open - what am I doing wrong? I have simpified stepwise by removing params and finally even this does not do.
var x=new jBox('Tooltip',{content:"Press Escape again to clear the input-field!"});
x.open();
I started with
var x = new jBox('Tooltip',{
content:"Press Escape again to clear the input-field!",
attach: "#ipExpr",
onInit: function() { this.open(); }
});
NB: I've chedcked that $("#ipExpr").length==1
It seems that attaching the jBox to an element and opening it when its being initialised seems to be the problem. Can you describe what kind of behavior your looking for in detail? For example, if you like to open the jBox right away on the element with id #idExpr, you could do it like this: jsfiddle.net/pbrrah37
var x = new jBox('Tooltip',{
content:"Press Escape again to clear the input-field!",
onInit: function() { this.open({target: $('#ipExpr')}); }
});

I've gone through: https://code.google.com/p/selenium/wiki/WebDriverJs and it doesn't have any information. So, can someone help.
I have
var element = driver.findElements(webdriver.By.id("something"))
console.log('text='+element.getAttribute("innerHTML"));
But doesn't work. Most of the documentation appears to be for JAVA not nodeJS. If you come across a .getText() function, I'm pretty sure that is JAVA. I actually just want the text part innerText, opposed to innerHTML. But that might be asking too much.
You can check innerHTML like this:
driver.executeScript(function() {
return document.querySelector('#something').innerHTML;
}).then(function(innerHTML) {
//check content here
});
Per the webdriver.js docs:
var myElement = element(by.css('.myclass'));
myElement.getInnerHtml().then(function(html) {
//do stuff with html here
});
Hope that helps! It's working for me using Node.js + Selenium / WebDriver, etc.
I'm using the wonderful plugin Leaflet.Control.Search in order to search for markers (from a geoJson marker group) on my map – which works great.
I only have one simple question now:
how can I open a popup for the search result marker?
I'm using custom marker icons with popups (which open on click) already bound to them – but I would like to open the respective popup automatically once it has been found via the search.
My code looks like this:
var searchControl = new L.Control.Search({layer: markers2, propertyName: 'Name', circleLocation:true});
searchControl.on('search_locationfound', function(e) {
e.layer.bindPopup(feature.properties.Name).openPopup();
}).on('search_collapsed', function(e) {
markers2.resetStyle(layer);
});
map.addControl( searchControl ); //inizialize search control
and thought it might work with that line:
e.layer.bindPopup(feature.properties.Name).openPopup();
but unfortunately it doesn't.. ;)
–
Oh, and a second question: at the moment I'm searching only in 1 geoJson layer ("markers2") – does anyone know whether it's possible to search in multiple layers at once?
Any suggestions? I'd be grateful for any help, thanks in advance!
got it: it works like this: e.layer.openPopup().openOn(map);
event.layer is set only for preloaded layer, if you search marker by ajax,jsonp or callData.. event.layer is undefined.
var geojsonLayer = new L.GeoJSON(data, {
onEachFeature: function(feature, marker) {
marker.bindPopup(feature.properties.name);
}
});
map.addLayer(geojsonLayer);
var controlSearch = new L.Control.Search({layer: geojsonLayer, initial: false});
controlSearch.on('search_locationfound', function(event) {
event.layer.openPopup();
});
Look at GeoJSON demo:
https://opengeo.tech/maps/leaflet-search/examples/geojson-layer.html
Recently, I was looking for an answer, and here is my solution for it
searchControl.on("search:locationfound", function (e) {
if (e.layer._popup) e.layer.openPopup();
});
I was wondering if there are ways to convert MathJax output to MathML.
I read through several articles that saying MathJax supports MathML. I can also see the option 'Show MathML' when I right click the MathJax formulas. My question is, can I get the MathML output to the webpage from MathJax? I am not familiar with MathJax and I am not sure how it works. Any resources or tutorial pages would have been nice!
#Peter, I think the OP may be asking how to get a MathML string from MathJax, rather than how to insert the MathML tags into the page directly. So perhaps the discussion on the MathJax forums that describes how to use toMathML will do the trick.
The basic idea is to get the element jax (using MathJax.Hub.getAllJax) for the math you want to convert, then to call its toMathML method. But you need to use some care for this, as toMathML can operate asynchronously. The link above goes through the details.
EDIT: The MathJax-node project allows you to do this from the command line, so you might want to check that out as well.
I have written some code check it out:
First include "https://code.jquery.com/jquery-1.11.2.min.js" and "http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"
var JaxToML = {
toMathML: function(jax, callback) {
var mml;
try {
mml = jax.root.toMathML("");
} catch (err) {
if (!err.restart) {
throw err
} // an actual error
return MathJax.Callback.After([JaxToML.toMathML, jax, callback], err.restart);
}
MathJax.Callback(callback)(mml);
},
convert: function(AjaxText, callback) {
var tempDiv = $('<div style="width:455px;height:450px:border-width:thick;border-style:double;"></div>').appendTo("body").html(AjaxText)[0];
MathJax.Hub.Queue(["Typeset", MathJax.Hub, tempDiv]); //first place in Q
MathJax.Hub.Queue(function() { //wait for a callback to be fired
var jax = MathJax.Hub.getAllJax(tempDiv);
for (var i = 0; i < jax.length; i++) {
JaxToML.toMathML(jax[i], function(mml) {//alert(jax[i].originalText + "\n\n=>\n\n"+ mml);
AjaxText = AjaxText.replace(jax[i].originalText, mml);
});
}
$(tempDiv).remove();
AjaxText = AjaxText.replace(/\(/g,""); //notice this escape character for ( - i.e it has to be \( , know why it is beacuse JS will treat ) or ( as end/begin of function as there are no quotes here.
AjaxText = AjaxText.replace(/\)/g,""); //notice this escape character for ) - i.e it has to be \)
AjaxText = AjaxText.replace(/\\/g,"");
callback(AjaxText);
});
},
};
Usage :
JaxToML.convert(AjaxText, function(mml) {
alert(mml);
});
The MathJax documentation on configuring MathJax is probably the place to start reading. You can configure the output jax per browser.
A word of caution. There's a reason why MathJax does not use to MathML output on any browser right now: browser support isn't quite there yet. (This will change as browsers catch up and MathJax can start to leverage their native support.) So make sure your content actually renders ok.
I am writing a Google extension. Here my content script modifies a page based on a list of keywords requested from background. But the new innerHTML does not show up on the screen. I've kluged it with an alert so I can see the keywords before deciding to actually send a message, but it is not how the routine should work. Here's the code:
// MESSAGE.JS //
//alert("Message Page");
var keyWordList= new Array();
var firstMessage="Hello!";
var contentMessage=document.getElementById("message");
contentMessage.value=firstMessage;
var msgComments=document.getElementsByClassName("comment");
msgComments[1].value="Hello Worlds!";//marker to see what happens
chrome.extension.sendRequest({cmd: "sendKeyWords"}, function(response) {
keyWordList=response.keyWordsFound;
//alert(keyWordList.length+" key words.");//did we get any keywords back?
var keyWords="";
for (var i = 0; i<keyWordList.length; ++i)
{
keyWords=keyWords+" "+keyWordList[i];
}
//alert (keyWords);//let's see what we got
document.getElementsByClassName("comment")[1].firstChild.innerHTML=keyWords;
alert (document.getElementsByClassName("comment")[1].firstChild.innerHTML);// this is a band aid - keyWords does not show up in tab
});
document.onclick= function(event) {
//only one button to click in page
document.onload=self.close();
};
What do I have to do so that the text area that is modified actually appears in the tab?
(Answering my own question) This problem really has two parts. The simplest part is that I was trying to modify a text node by setting its value like this:
msgComments1.value="Hello Worlds!"; //marker to see what happens
To make it work, simply set the innerHTML to a string value like this:
msgComment1.innerHTML="Hello Worlds!"; //now it works.
The second part of the problem is that the asynchronous call to chrome.extension.sendRequest requires a callback to update the innerHTML when the reply is received. I posted a question in this regard earlier and have answered it myself after finding a solution in an previous post by #serg.
How do I get a reference to the dom of a cross domain iframe/frame?
I want to do some stuff to disqus comments with an extension.
My manifest has the following:
"all_frames": true,
"matches": ["*://*.disqus.com/*","*://disqus.com/*", "http://somesite.com"]
I am not trying to communicate outside of the frame - that is the js will take care of the work without needing to 'tell' me anything.
all_frames should inject the listed js files into every frame, no?
When I do this:
if (window != window.top){
alert('In an IFRAME: ' + window.location.href);
}
...I get the expected disqus URLs.
But when I do this:
var btnCommentBlock = document.getElementsByClassName('dsq-comment-buttons');
alert('btnCommentBlock length: ' + $(btnCommentBlock).length);
...I get 0 for length.
I updated my answer to Javascript to access Disqus comment textbox?
Basically, Disqus changed the selector. They no longer use textarea, they use contenteditable divs.
Something like this should work:
// We just need to check if the IFrame origin is from discus.com
if (location.hostname.indexOf('.disqus.com') != -1) {
// Extract the textarea (there must be exactly one)
var commentBox = document.querySelector('#comment');
if (commentBox) {
// Inject some text!
commentBox.innerText = 'Google Chrome Injected!';
}
}

Woohoo! I found the answer on github:
https://gist.github.com/471999
The working code is:
$(document).ready(function() {
window.disqus_no_style = true;
$.getScript('http://sitename.disqus.com/embed.js', function() {
var loader = setInterval(function() {
if($('#disqus_thread').html().length) {
clearInterval(loader);
disqusReady();
}
}, 1000);
});
function disqusReady() {
//whatever you can imagine
}
});
I put this in the disqusReady() function:
var aTestHere = document.getElementsByClassName('dsq-comment-body');
alert(aTestHere[0].innerHTML);
...and got back the innerHTML as expected.
Mohamed, I'd really like to thank you for taking the time to interact with my question. If you hadn't posted that link to github there's no telling when if ever I'd have figured it out or found the other code.
edit: After a few minutes of experimenting it looks like it is not necessary to call getScript so you should be able to comment that out.
Also unnecessary is window.disqus_no_style so I commented that out too.
I'll experiment some more and update the answer later. One of those two things prevented me from being able to actually post a comment at the disqus site I use. //them out still allows access to the dom and the ability to post.
