How to Use carriage return to replace the TAB when entering a form _ form Effect

When filling out a form, use carriage return instead of TAB. The key is tabindex, which is designed to set a tabindex for each form element, the value is the value of tabindex of the previous form Element plus one. The function is to add one value of the current tabindex when you press the Enter key, then compare them one by one with the tabindex value of each form element. If they are equal, move the focus to the form element.

First, we need to set an onkeyup event in the form body:


Second, set a tabindex value for each form element. Assuming that the form has three elements, we set the tabindex values as follows:




Finally, write the changefocus function as follows:
Function newinfo_form_onkeyup ()
{
Key = window. event. keyCode;
If (key = 0xD) // determines whether to press the Enter key
{
CurTabIndex = event. srcElement. tabIndex 1 // Add the value of the current tabindex to 1
For (n = 0; n {
If (newinfo_form.elements [n]. tabIndex = CurTabIndex) // locate the next form Element
{
Newinfo_form.elements [n]. focus (); // move the focus
Return true;
}
}
}
}
