In an HTML form, a be taken as limitations to the amount of data.
The HTML specifications have explicitly said that from the very beginning; the HTML 2.0 specification said: "HTML user agents should allow text to extend beyond these limits by scrolling as needed", and the current specification, HTML 4.01, repeats this more verbosely: This attribute specifies the number of visible text lines.
As I mentioned at the start of the article, I have gathered all of the code from this article, sprinkled some extra code for resilience in case any of the browsers decide to drop support for undocumented features the code relies on and published it as an npm package.
Especially in applications where data is entered to a database or stored onto disk on the server, some limitations must be imposed on the amount of data.
Users should be able to enter more lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area.
This attribute specifies the visible width in average character widths.
Browsers may impose some limitations, but they are a problem, not a solution.
The server-side script that handles the form submission needs to check against excessive amount of input.
I have everything in my code working properly except for the fact that the payment amounts are being displayed in the command window and I need to display them in the text area, as well as adding scroll bars to the text area.If we try to push the size of the data in the textarea even further, things become truly grim.On a sizeable 500kb document I’m getting 0.5-second to 2.5-second delay depending on the browser and the document, that are unacceptable. At this point, I remembered about and was pleasantly surprised that it does work with textareas and inputs in most browsers (Chrome, Opera, Safari, Edge)./** * Spawns an error dialogue detailing the given exception.
