I use CodeMirror V. 3 for stand alone syntax highlighting (other parts of my project also uses the CodeMirror editor, so I don't want to use other standalone-syntax highlighting libraries like google-code-prettify).
I use the lib/runmode.js script as described in the CodeMirror: Mode Runner Demo to highlight code in a <pre>-tag. This works fine. Now I want to add line numbers on the left side of the code just like in the CodeMirror editor.
(The CodeMirror.runMode have an options argument, but this seems to work only with the tabsize. Any idea how I can add linenumbers to my code (like in google-code-prettify the css-class linenums)?)
I would hack Mode Runner like this
CodeMirror.runMode = function(string, modespec, callback, options) {
var mode = CodeMirror.getMode(CodeMirror.defaults, modespec);
var lineNumber = 1; // Line number
if (callback.nodeType == 1) {
var tabSize = (options && options.tabSize) || CodeMirror.defaults.tabSize;
var node = callback, col = 0;
node.innerHTML = "";
callback = function(text, style) {
if (text == "\n") {
lineNumber++ ; //increment line number
var lineNum = document.createTextNode(lineNumber); //
node.appendChild(document.createElement("br"));
node.appendChild(lineNum); // append
col = 0;
return;
}
var content = "";
// replace tabs
for (var pos = 0;;) {
var lineNum = document.createTextNode(lineNumber + " ")
var idx = text.indexOf("\t", pos);
if (idx == -1) {
content += text.slice(pos);
col += text.length - pos;
break;
} else {
col += idx - pos;
content += text.slice(pos, idx);
var size = tabSize - col % tabSize;
col += size;
for (var i = 0; i < size; ++i) content += " ";
pos = idx + 1;
}
}
if (style) {
var sp = node.appendChild(document.createElement("span"));
sp.className = "cm-" + style.replace(/ +/g, " cm-");
sp.appendChild(document.createTextNode(content));
} else {
node.appendChild(document.createTextNode(content));
}
};
}
var lines = CodeMirror.splitLines(string), state = CodeMirror.startState(mode);
for (var i = 0, e = lines.length; i < e; ++i) {
if (i) callback("\n");
var stream = new CodeMirror.StringStream(lines[i]);
while (!stream.eol()) {
var style = mode.token(stream, state);
callback(stream.current(), style, i, stream.start);
stream.start = stream.pos;
}
}
// add the first line
var outputDiv = document.getElementById("output");
var firstLine = document.createTextNode("1 ");
outputDiv.insertBefore(firstLine, outputDiv.firstChild);
};

The code below is for listing blogger posts within a Label Name, if the post has the specific Label Name it will be shown in this list. I would like to be able to change the appearance of how everything is displayed by changing where the post image would look, and where the title would look, change background color, add borders, shadows change the font etc ...(I know how to change the appearance with css, but I do not know how to integrate the code below with css and html) At the moment the code shows the title and the right of the title the image.

This creates stuff you can style with CSS. For example:
#postList12 li {
border: 1px solid blue;
}
Use the inspector in your browser to see what it makes. If you want to change the order of elements or add new ones you’ll have to edit the script to do that.
I'm not a programmer, but trying to write a script for Photoshop. Below is something that I found, but it simply increments the files "1.png, 2.png, etc..." I'd like to name the exported files, "documentName_canvasWidth_canvasHeight_incrementedNumber.png"
function sfwPNG24(saveFile){
var pngOpts = new ExportOptionsSaveForWeb;
pngOpts.format = SaveDocumentType.PNG
pngOpts.PNG8 = false;
pngOpts.transparency = true;
pngOpts.interlaced = false;
pngOpts.quality = 100;
activeDocument.exportDocument(new File(saveFile),ExportType.SAVEFORWEB,pngOpts);
}
/*
Incrementing a number inside a text layer then Saving it in PNG
*/
var layer = activeDocument.layers[0];
if (layer.kind == 'LayerKind.TEXT') {
for (var i=1; i < 7; i++) {
layer.textItem.contents = i.toString();
sfwPNG24( 'filepathgoeshere'+ i +'.png');
};
};
Add these changes to the second part of the code:
var layer = activeDocument.layers[0];
// documentName_canvasWidth_canvasHeight_incrementedNumber.png
var srcDoc = app.activeDocument;
// get width and height
var W = srcDoc.width.value;
var H = srcDoc.height.value;
// get document name
var fn = srcDoc.name;
if (layer.kind == 'LayerKind.TEXT')
{
for (var i=1; i < 7; i++)
{
layer.textItem.contents = i.toString();
sfwPNG24( 'filepathgoeshere'+ W + "_" + H + "_" + i +'.png')
}
}

I'm having troubles with the syntax of the line "$("theWords[i]......."
I realize how simple of a question this is, and not academic to the community, but I have been fumbling with this syntax for awhile and can't find any specific forum to correct my syntax error.
I am attempting to have the font size change according to the amount of times the word appears in a document.
wordCount = count of appears.
theWords = all words I would like to have the rule applied to
I manage to have something working with what you did using a bit more of jQuery to build the list of words to show. hope it helps :D.
$(document).ready(function() {
var data = $(".sometext").text();
wordCount = {}; theWords = []; allWords = data.match(/\b\w+\b/g); //get all words in the document
for (var i = 0; i < allWords.length; i++){
allWords[i] = allWords[i].toLowerCase();
var word = allWords[i];
if (word.length > 5) {
if (wordCount[word]) {
wordCount[word] = wordCount[word] + 1;
} else {
wordCount[word] = 1;
}
}
}
var theWords = Object.keys(wordCount); // all words over 5 characters
for(var i = 0; i < theWords.length; i = i + 1) {
$('<span/>', {
'text': theWords[i] + " ",
'class': theWords[i]
}).appendTo('.result');
}
for(var i = 0; i < theWords.length; i++) {
$("." + theWords[i]).css("font-size", 15 + wordCount[theWords[i]]*5 + "px");
}
});

I have uploaded the XML screenshot. The structure of the xml is divided into levels, So based on a level I need only the levels which are below it.
For example level 1 can be identified by Name and Code tag so I want level 2 of a specific level 1 for which the code matches.
I have written the Javascript for parsing this XML but I am not get what I need
$('#permissionproperty_1').on("change",function () {
var code = $(this).val().trim();
var i;
var xmlDoc;
//var xml = "<rss version='2.0'>" + $('#hidXML').val() + "</rss>";
var xml = "<xml version='1.0'>" + $('#hidXML').val() + "</xml>";
var xmlDoc = $.parseXML(xml);
var nodes = $(xmlDoc).find('Node')
//alert(nodes.length);
for (j = 0; j < nodes.length; j++) {
var level = nodes[j].getAttribute('level');
if (level == 1) {
var name = nodes[j];
var na = $(name).length;
var child = $(name).find('Code').text().trim();
if (child.indexOf(code) != -1) {
for (i = 0; i < na; i++) {
var level1 = nodes[i].getAttribute('level');
if (level1 == 2) {
var name1 = $(node[i]).find('Node').find('Name').text().trim();
var code1 = $(node[i]).find('Node').find('Code').text().trim();
alert(name1 + " : Name code :" + code1);
}
}
}
}
}
});
When I type in a non-resizeable text area something like hello world, this is a demo and the text area is small enough, it will look like this:
hello world,
this is a demo
This is not caused by a \n or something.
How can I detect this natural line break in a text area?
A fiddle can be found here: http://jsfiddle.net/yx6B7/
As you can see, there is a line break, but javascript just says that it's one big line without any line-breaks in it.
Finally I found this script on the internet:
function ApplyLineBreaks(strTextAreaId) {
var oTextarea = document.getElementById(strTextAreaId);
if (oTextarea.wrap) {
oTextarea.setAttribute("wrap", "off");
}
else {
oTextarea.setAttribute("wrap", "off");
var newArea = oTextarea.cloneNode(true);
newArea.value = oTextarea.value;
oTextarea.parentNode.replaceChild(newArea, oTextarea);
oTextarea = newArea;
}
var strRawValue = oTextarea.value;
oTextarea.value = "";
var nEmptyWidth = oTextarea.scrollWidth;
var nLastWrappingIndex = -1;
for (var i = 0; i < strRawValue.length; i++) {
var curChar = strRawValue.charAt(i);
if (curChar == ' ' || curChar == '-' || curChar == '+')
nLastWrappingIndex = i;
oTextarea.value += curChar;
if (oTextarea.scrollWidth > nEmptyWidth) {
var buffer = "";
if (nLastWrappingIndex >= 0) {
for (var j = nLastWrappingIndex + 1; j < i; j++)
buffer += strRawValue.charAt(j);
nLastWrappingIndex = -1;
}
buffer += curChar;
oTextarea.value = oTextarea.value.substr(0, oTextarea.value.length - buffer.length);
oTextarea.value += "\n" + buffer;
}
}
oTextarea.setAttribute("wrap", "");
document.getElementById("pnlPreview").innerHTML = oTextarea.value.replace(new RegExp("\\n", "g"), "<br />");
}
Which is working fine.
This isn't a javascript problem.
Look at the word-wrap, white-space and overflow css properties.
