– Check Browser Compatibility
The content materialEditready and designMode properties might not be supported in all browsers. Use function detection to make sure they’re supported earlier than setting the values.
Here is an instance of checking browser compatibility in JavaScript:
| // Check if the browser helps the content materialEditready property
if (‘contentEditable’ in doc.physique) { // If it does, set the content materialEditready property to true doc.physique.content materialEditready = ‘true’; } else { // If it doesn’t, present an error message console.error(‘Your browser does not support the contentEditable property.’); } // Check if the browser helps the designMode property if (‘designMode’ in doc.physique) { // If it does, set the designMode property to on doc.designMode = ‘on’; } else { // If it doesn’t, present an error message console.error(‘Your browser does not support the designMode property.’); } |
In this instance, the code checks if the content materialEditready and designMode properties can be found within the doc.physique object. If they’re, the code units them to the acceptable values. If not, it logs an error message to the console indicating that the properties will not be supported within the present browser.
– Feature Detection
“Use feature-detecting code” means checking if sure properties or APIs can be found within the present browser earlier than utilizing them. This helps make sure the code runs appropriately throughout totally different browsers and avoids errors.
For instance, the consumer can use the next code to examine if the content materialEditready property is supported within the present browser:
| if (‘contentEditable’ in doc.physique) {
doc.physique.content materialEditready = ‘true’; } else { console.log(‘contentEditable is not supported in this browser’); } |
In this code, the if assertion checks if the content materialEditready property is current within the doc.physique object. If it’s, then it units the content materialEditready property to true. If it’s not, it logs a message to the console indicating that content materialEditready will not be supported on this browser.
By utilizing function detection, the consumer can be sure that their code runs appropriately and easily throughout totally different browsers with out encountering errors or sudden conduct.
Let’s take one other instance to know this:
| if (doc.physique.content materialEditready !== undefined) {
doc.physique.content materialEditready = ‘true’; } else { // do one thing else } if (doc.designMode !== undefined) { doc.designMode = ‘on’; } else { // do one thing else } |
– Feature Checking
“Feature checking” is a method utilized in software program improvement to find out if a selected function is on the market within the atmosphere, usually an online browser, earlier than utilizing it. The thought behind function checking is to keep away from errors which will happen when a browser doesn’t help a function that the code is making an attempt to make use of.
In the context of the error “document.body.contenteditable = ‘true’; document.designmode=’on’; void 0”, function checking can be utilized to decide if the browser helps the contenteditable and designmode properties of the doc object earlier than trying to set their values.
Here’s an instance of use function checking:
| strive {
doc.physique.content materialEditready = ‘true’; doc.designMode = ‘on’; } catch (e) { // deal with the error } |
In this instance, the code units the contenteditable and designmode properties inside a strive block. If an error happens, akin to if the browser doesn’t help these properties, it’s caught and dealt with within the related catch block. The precise dealing with of the error will rely upon the precise necessities of your software. For instance, the consumer would possibly present a special, various answer that also meets their wants.
– Try-Catch Statement
A “Try-Catch Statement” is a typical programming assemble used to deal with exceptions or errors which will happen through the execution of a program. It consists of two components: a strive block and a catch block. The code which will throw an error is positioned inside the strive block. If an error happens, this system jumps to the related catch block, the place the error might be dealt with. This will eradicate the doc physique contenteditable true’; doc designmode on the error message.
The Try-Catch Statement is usually used to deal with sudden or distinctive circumstances in a program, akin to file I/O errors, community errors, or invalid consumer inputs. By utilizing a Try-Catch Statement, the consumer can write extra strong code that may deal with errors gracefully as a substitute of simply crashing or producing unpredictable outcomes.
Here’s a easy instance of a Try-Catch Statement in JavaScript:
| strive {
let x = y + 1; // y is undefined, so this line will throw a ReferenceError } catch (e) { console.error(e); // logs “ReferenceError: y is not defined” } |
In the instance, the code within the strive block makes an attempt to carry out a calculation with the y variable, which is undefined. This leads to a ReferenceError, which is caught by the catch block. The error message is then logged into the console.

– Use Correct Syntax
Using the proper syntax means utilizing a programming language’s correct and standardized syntax to put in writing the code. Proper syntax ensures that the code is comprehensible by people and computer systems and helps keep away from errors or sudden conduct.
For instance, in JavaScript, the appropriate syntax for an “if” assertion is as follows:
| if (situation) {
// code can be executed when the situation is true } |
In this instance, the if key phrase is adopted by a situation in parentheses, and the code will execute when the situation is true and is enclosed in curly braces {}. To keep away from this error message, it’s essential to make use of the proper syntax and comply with established coding requirements and conventions.
Moreover, through the use of appropriate syntax, the programmer can eliminate varied different error messages, akin to:
- physique.contenteditable=’true’ not working.
- physique.contenteditable = true void 0 chrome.
– Use Proper Functions
Use the code “(function(){document.body.contenteditable = ‘true’;document.designmode = ‘on’;})();” to eradicate the error message. It is an nameless operate that’s instantly executed. A generally requested query, “how to edit any website” might be answered and resolved through the use of this code to allow enhancing.
The nameless operate units the “contenteditable” attribute of the “body” component to “true” and the “designmode” property of the doc object to “on”, which makes the doc editable. This permits content material enhancing for the net web page, permitting customers to edit the web page straight within the browser.
The parenthesis on the finish of the code () is used to right away execute the operate, that means will probably be executed as quickly because it’s outlined. This sample can also be known as “Immediately Invoked Function Expression” (IIFE).
| <button id=”editBtn”>Edit</button>
<script> doc.getElementById(‘editBtn’).addEventListener(‘click’, operate() { (operate(){ doc.physique.content materialEditready = ‘true’; doc.designMode = ‘on’; })(); }); </script> |
In this code, a button with an id of “editBtn” is created, and a click on occasion listener is added to the button utilizing JavaScript. When the button is clicked, the nameless operate units the “contenteditable” attribute of the “body” component to “true” and the “designmode” property of the doc object to “on”. This permits customers to edit textual content or edit any web site (javascript) straight within the browser.
