Paste from clipboard in overwrite mode - input cursor moves to the end of text node

Our target browser is IE8 as the application is a legacy one and has got some com dependency.We are showing content inside a content-editable div. One of the requirements is to be able to replace texts inside the div when the browser is in "overwrite" mode. Paste is working fine but the input cursor is always moving to the end after the paste. We are using rangy-core, version: 1.3.1 for range/selection related logic. Unable to figure out what is going wrong here. Need help.
The following code is called when the document is loaded:
$("#info").on("paste", function (e) {
var clipboardData = window.clipboardData.getData("Text");
clipboardData = clipboardData.replace(/(^ *)|(\r\n|\n|\r)/gm, "");
if (isOverwriteEnabled()) {
e.preventDefault ? e.preventDefault() : e.returnValue = false;
pasteCopiedData(clipboardData);
}
});
Related code snippets for reference:
function isOverwriteEnabled() {
try {
// try the MSIE way
return document.queryCommandValue("OverWrite");
} catch (ex) {
// not MSIE => not supported
return false;
}
}
function pasteCopiedData(clipboardData) {
var json = getCurrentNodeWithOffset();
handleTextOverwrite(json, clipboardData);
}
function getCurrentNodeWithOffset() {
var json = {};
var selectedObj = rangy.getSelection();
var range = selectedObj.getRangeAt(0);
json.node = selectedObj.anchorNode.nodeType === 3 ? selectedObj.anchorNode : findImmediateTextNode(selectedObj.anchorNode, range.startOffset);
json.offset = selectedObj.anchorNode.nodeType === 3 ? range.startOffset : json.node.nodeValue.length - 1;
return json;
}
function handleTextOverwrite(json, textToReplace) {
var lenToCopy = textToReplace.length;
var offsetPos = json.offset;
var jsonNode = json.node;
try {
while (lenToCopy > 0) {
var toCopy = jsonNode.nodeValue.length - offsetPos;
var startPos = textToReplace.length - lenToCopy;
if (lenToCopy <= toCopy) {
json.node.nodeValue = jsonNode.nodeValue.substr(0, offsetPos) + textToReplace.substr(startPos) + jsonNode.nodeValue.substr(offsetPos + lenToCopy);
lenToCopy = 0;
}
else {
var copiedPos = startPos + toCopy;
jsonNode.nodeValue = jsonNode.nodeValue.substr(0, offsetPos) + textToReplace.substr(startPos, toCopy);
lenToCopy -= copiedPos;
var nextJsonNode = findNextTextNode(jsonNode);
if (!nextJsonNode) {
//do the remaining paste in jsonNode
jsonNode.nodeValue = jsonNode.nodeValue + textToReplace.substr(copiedPos);
lenToCopy = 0;
}
else {
jsonNode = nextJsonNode;
}
}
offsetPos = 0;
}
setCaret(json.node, json.offset);
}
catch (ex) {
}
}
function setCaret(node, pos) {
var el = document.getElementById("info");
var rangyRange = rangy.createRange(el);
var sel = rangy.getSelection();
rangyRange.setStart(node, pos + 1);
rangyRange.setEnd(node, pos + 1);
rangyRange.collapse(true);
sel.removeAllRanges();
sel.addRange(rangyRange);

How can I refer to a local js file?

I have a js file that I can't refer to locally.
If I deploy it online and refer to it from there, it works.
<script src="http://acwebsite.azurewebsites.net/scripts/table2excel.js"></script>
But if I copy the text inside the file and refer to a local js file, it is unable to read it.
<script src ="~/Scripts/table2excel.js"></script>
Not sure what to do.

// more objects, storing the result in the first object. The first object
// is generally empty as we don't want to alter the default options for
// future instances of the plugin

Regex to change a html element class with javascript not working

I have the following javascript function to open and close sub list elements on an onclick event:
function ShowHideDtls(itId) {
var subMen = document.getElementById(itId);
if (subMen != null) {
if (subMen.className == "nav nav-second-level collapse in") {
subMen.className = "nav nav-second-level collapse";
} else {
subMen.className += " in";
}
}
}
The "collapse" is a css class which makes display=none hiding the sub list and "in" is a class which makes display=block showing the sub list, creating a menu with submenus.
I found in this question Change an element's class with JavaScript in the first(accepted) answer use of a regex in order to do this. I tried it like this:
function ShowHideDtls(itId) {
var subMen = document.getElementById(itId);
if (subMen != null) {
if (subMen.className.match(/(?:^|\s)in(?!\S)/)) {
subMen.className.replace(/(?:^|\s)in(?!\S)/g, '');
} else {
subMen.className += " in";
}
}
}
The code without the regex works perfectly but with the regex it doesn't. I checked the regex in regex101.com and it seems to work there. As I understand it's more appropriate to use the regex than a long string of all the class names and also I also have a nav-third-level class that I have to close and open so the regex seems to be the convenient and proper way to do it.
What's wrong?
Thank you.

No need of regex here. You can use classList
Using classList is a convenient alternative to accessing an element's list of classes as a space-delimited string via element.className.
function ShowHideDtls(itId) {
var subMen = document.getElementById(itId);
if (subMen != null) {
subMen.classList.toggle('in');
}
}
toggle() will toggle the class of the element. If the element already has the class, it'll remove it, if not then toggle will add the class to the element.
Check the Browser Compatibility.
You can use following SHIM from MDN for IE9,

If you're using jQuery, you can use toggleClass():
function ShowHideDtls(itId) {
$('#' + itId).toggleClass('in');
}
Edit
If you still want to use regex:
if (/\bin\b/.test(subMen.className))
subMen.className.replace(/\bin\b/, '');
} else {
subMen.className += " in";
}
You can also use split() and indexOf as follow to check if a class is present on element.
var classes = className.split(/\s+/),
classIndex = classes.indexOf('in');
if (classIndex > -1) {
classes.splice(classIndex, 1);
subMen.className = classes.join(' ');
} else {
subMen.className += " in";
}

replace function returns the resultant value, it do not assign value indirectly.
So do following:
function ShowHideDtls(itId) {
var subMen = document.getElementById(itId);
if (subMen != null) {
if (subMen.className.match(/(?:^|\s)in(?!\S)/)) {
subMen.className = subMen.className.replace(/(?:^|\s)in(?!\S)/g, '');
}
else {
subMen.className += " in";
}
}
}

The script doesn't support chrome. Read through it in most of the functions like checkForUrlChange() it looks at the name of the browser to decide what to do.
Because chrome and safari are both based on webkit, you can try to change the line useragent.indexOf("safari") != -1 to useragent.indexOf("safari") != -1 || useragent.indexOf("chrome") != -1 to see if that works.
If not, try using unfocus history keeper. It supports Chrome.

First, Firebug is your friend, get used to it. Second, if you paste each function and some supporting lines, one by one, you will eventually get to the following.
var DebugMode = (getQueryVariable("debug")=="1")
function getQueryVariable(variable)
You can't execute getQueryVariable before it is defined, you can create a handle to a future reference though, there is a difference.
There are several other potential issues in your code, but putting the var DebugMode line after the close of the getQueryVariable method should work fine.

It would help if you gave more context. For example, is
Failed to load source for:
http://localhost/js/m.js
the literal text of an error message? Where and when do you see it?
Also, does that code represent the contents of http://localhost/js/m.js? It seems that way, but it's hard to tell.
In any case, the JavaScript that you've shown has quite a few statements that are missing their semicolons. There may be other syntax errors as well. If you can't find them on your own, you might find tools such as jslint to be helpful.

make sure the type attribute in tag is "text/javascript" not "script/javascript".

I know it is more than a year since this question was asked, but I faced this today. I had a
<script type="text/javascript" src="/test/test-script.js"/>
and I was getting the 'Failed to load source for: http://localhost/test/test-script.js' error in Firebug. Even chrome was no loading this script. Then I modified the above line as
<script type="text/javascript" src="/test/test-script.js"></script>
and it started working both in Firefox and chrome. Documenting this here hoping that this will help someone. Btw, I dont know why the later works where as the previous one didn't.
