I have the following function which fires when clic开发者_开发百科ked but how would I also make it fire on enter without creating a new function? (if possible).
$("#jump_menu select option").click(function(){
var hash = $(this).val();
var target_offset = $(hash).offset();
$('html, body').animate({scrollTop:target_offset.top}, 500);
})
Try binding to
$("#jump_menu select").change
...instead.
Alternatively just move it to a standalone function and bind to what you need:
function handler(elem) {
var hash = $(elem).val();
var target_offset = $(hash).offset();
$('html, body').animate({scrollTop:target_offset.top}, 500);
}
$('#jump_menu select option').click(handler);
$('#jump_menu select').change(handler);
You may need to save and compare event timestamps though to ensure you don't call your handler twice for a single selection.
You have to globally declare your function, rather than declaring it in your .click function like so:
function animateBody() {
var hash = $(this).val();
var target_offset = $(hash).offset();
$('html, body').animate({scrollTop:target_offset.top}, 500);
}
After that, you can bind the function to multiple event without redeclaring it twice:
$("#jump_menu select option").click(animateBody);
$("#jump_menu select").change(animateBody);
The resulting could look something like this:
//Other JQuery/Javascript
function animateBody() {
var hash = $(this).val();
var target_offset = $(hash).offset();
$('html, body').animate({scrollTop:target_offset.top}, 500);
}
$("#jump_menu select option").click(animateBody);
$("#jump_menu select").change(animateBody);
//Other JQuery/Javascript
Good luck!
function runAnimate() {
var hash = $(this).val();
var target_offset = $(hash).offset();
$('html, body').animate({scrollTop:target_offset.top}, 500);
}
$("#jump_menu select option").click(runAnimate);
$('body').change(runAnimate);
$(selector).on('keyup , change' ,function() {
--- Do some thing ---
});
