How to remove the "Enter" in the form, "Submit" and "Enter != Submit"
|
To implement the "Enter != Submit" problem, you can generally start from the "button type" and "number of input boxes". By default, for a single input box, regardless of whether the button is type="submit" or type="button", pressing Enter means submitting. 1. When type="submit", no matter how many type="text" input boxes there are, pressing Enter means submit. （submit） 2. When type="button" and there are multiple input boxes, pressing Enter does not submit. (button) 3. To solve the problem of submitting when pressing Enter in a single input box, refer to the second point: you can add an input="text" and hide it; then set the type to button. In actual applications, there is rarely only one input box, so you only need to remember the second rule to deal with it. Using JS events to prevent form submission is beyond the scope of this article, but it is certainly possible. |
