一直都嫌下拉框这个html控件难看,之前弄了个<div><ul><li></li></ul></div>版的下拉框
觉得这个下拉框已经稍微能满足美观需求了,
这个是点出来的效果,写了键盘的方向键,回车,esc等 事件, 并且能根据页面的底部距离判断是否向上展示
今天弄了个联动的,顺便贴部分代码
效果预览:
以下代码解决了ie6的兼容问题
$containerDivText.mousedown(function() {
setTimeout(
function() {
if ($newUl[0].style.display == 'block') {
$newUl.hide();
positionHideFix();
return false;
}
$containerDiv.focus();
//show list
$newUl.slideDown(100);
positionFix();
//when keys are pressed
document.onkeydown = function(e) {
if (e == null) { // ie
var keycode = event.keyCode;
} else { // everything else
var keycode = e.which;
}
//enter key or esc key pressed, hide list
if (keycode == 13 || keycode == 27) {
$newUl.hide();
positionHideFix();
return false;
}
}
}, 1);
//the function settimeout is used for ie6, because if you click the element where you hava focused on the element,
//ie6 would think you click it twice(2010-2-4)
});
setTimeout(
function() {
if ($newUl[0].style.display == 'block') {
$newUl.hide();
positionHideFix();
return false;
}
$containerDiv.focus();
//show list
$newUl.slideDown(100);
positionFix();
//when keys are pressed
document.onkeydown = function(e) {
if (e == null) { // ie
var keycode = event.keyCode;
} else { // everything else
var keycode = e.which;
}
//enter key or esc key pressed, hide list
if (keycode == 13 || keycode == 27) {
$newUl.hide();
positionHideFix();
return false;
}
}
}, 1);
//the function settimeout is used for ie6, because if you click the element where you hava focused on the element,
//ie6 would think you click it twice(2010-2-4)
});
