Why You’re Failing at document.body.contenteditable = ‘true’; document.designmode=’on’; void 0
This is an example of the HTML for a form that will submit the form values to the server. The document.body.contenteditable option is used to ensure that the form values are filled in once the form is submitted, and the document.designmode option is used to display the form on the page.
We just got a request to send a form to a page that doesn’t exist. It’s a simple form that will be filled out once submitted, and it’s using a default value of false. The following line will ensure that it gets submitted: document.body.contenteditable = ‘true’; document.
body.contenteditable: true; is used in conjunction with the document.designmode option. This is one of the ways that the browser determines how to display the form. This is a very powerful control, and is one of the key areas of the documentation. Basically, using the document.designmode option can ensure that the client side is displaying the form properly. The document.body.
This is really a “can’t get enough” type of feedback. It’s not always a “please help me out and tell me what I do wrong.” It’s more like “I’m a beginner so I can’t even figure out what this is. Please help.” In the case of document.body.contenteditable, it’s a double negative.
The document.body.contenteditable property is a very powerful control. It allows you to create HTML elements like textareas, input fields, tables, divs, and more. Once it is set to true, it will display the form, the controls within the form, and the body of the form. This is one of the key areas of the documentation, as it is the area that allows you to provide the client side the most input. You can also use the document.
In the case of document.body.contenteditable, we can’t really do anything about it. It is entirely left to the user’s abilities to provide input. But we should also note the use of the document.documentElement.contentEditable = ‘true’; The use of this attribute is particularly powerful, as it allows the document to be edited by the client side.
Of course, the document.documentElement.contentEditable is already set to true. But what if we did want to change the value of the data stored in the html file, but we didn’t have the ability to edit the data in the html file itself? In this case, we can use the document.body.contenteditable attribute to allow this. This will allow us to access the data stored in the HTML file, but not edit it.
I had a lot of fun with this little trick. It works just like it sounds. When you want to access the data in the HTML file, you can give it the document.body.contenteditable attribute and it will allow you to access the data stored in the html file, but it won’t be editable. You can change the value stored in the html file, but not the data in the html file itself.
