javascript - vertical - Desplácese por un desbordamiento div desplazándose en cualquier lugar de la página
scroll height css (2)
puede configurar el desbordamiento: oculto para div. y configurar css para deseleccionar el contenido div.
var clicking = false;
var position;
var scrollpos;
$(window).mousedown(function(e){
clicking=true;
position = e.pageY;
});
$(window).mouseup(function(){
clicking = false;
})
$(window).mousemove(function(e){
if(clicking == false)
return;
scrollpos=$(''#scrollMeToo'').scrollTop();
$(''#scrollMeToo'').scrollTop(scrollpos + (e.pageY-position)) ;
})
Me gustaría desencadenar el desplazamiento de un div con contenido desbordado desplazándome a cualquier parte de la página, no solo moviendo el mouse y haciendo clic dentro de div. Además, me gustaría ocultar la barra de desplazamiento del div de modo que solo la barra de desplazamiento de la página esté visible.
Preferiblemente, la solución estaría basada en CSS, pero una solución JS también funcionaría.
aquí está mi jsfiddle que demuestra el problema: http://jsfiddle.net/trpeters1/RMZsX/8/
Copiaba el código aquí, pero allí pongo un montón de texto de relleno para activar las barras de desplazamiento.
Sin embargo, para su referencia, el nombre del div interno que me gustaría desplazar al desplazarme por la página tiene un id="scrollMeToo" .
var curScroll = 0;
$(window).bind(''mousewheel DOMMouseScroll'', function(e){
var evt = window.event || e;
var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
if(delta < 0) {
//scroll down
curScroll += 10;
}
else {
//scroll up
curScroll -= 10;
}
$(''#scrollMeToo'').scrollTop(curScroll);
return true;
});
#scrollMeToo {
height: 200px;
width:150px;
overflow: auto;
position: relative;
overflow-y: hidden;
}

Para cambiar la velocidad de desplazamiento, simplemente modifique este bloque para adaptarlo a sus necesidades:
if(delta < 0) {
//scroll down
curScroll += 10;
}
else {
//scroll up
curScroll -= 10;
}
Simplemente cambie los 10 valores a lo que necesite.
Actualizar:
var curScroll = 0;
$(window).on(''mousewheel DOMMouseScroll'', ''body'', function(e){
var evt = window.event || e;
var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
var loc = $(''#scrollMeToo'').scrollTop() + $(''#scrollMeToo'').innerHeight();
var height = $(''#scrollMeToo'')[0].scrollHeight - 10;
var height2 = $(''#scrollMeToo'')[0].scrollHeight - $(''#scrollMeToo'').innerHeight();
if(delta < 0) {
//scroll down
if (curScroll < height2) {
curScroll += 10;
}
}
else {
//scroll up
if (curScroll > 0) {
curScroll -= 10;
}
}
if (loc >= height && !$(''#scrollMeToo'').hasClass(''appended'')) {
var moreContent =''<a href="google.com">a link</a>'';
$(''#scrollMeToo'').append(moreContent);
$(''#scrollMeToo'').addClass(''appended'');
console.log(''appended'');
}
$(''#scrollMeToo'').scrollTop(curScroll);
return true;
});
Esta modificación debe adaptarse a sus necesidades, de acuerdo con lo que ha descrito. También modifiqué ligeramente la función para algunas correcciones generales.
El contenido aparecerá justo antes de que se llegue a la parte inferior de la div, y solo aparecerá una vez.
