如下所示,我试图绘制数字圈,但我希望这个圈子始终从0开始,我怎样才能实现这种行为。
另外我想将内圈边界的数字用虚线连接到数字,我怎么画虚线

function createFields() {
$('.field').remove();
var container = $('#container');
for(var i = 0; i < +$('input:text').val()+1; i++) {
$('<div/>', {
'class': 'field',
'text': i
}).appendTo(container);
}
}
function distributeFields() {
var fields = $('.field'), container = $('#container'),
width = center.width()*2, height = center.height()*2,
angle = 0, step = (2*Math.PI) / fields.length;
var radius = width/2;
var containerLength=$('input:text').val();
angle=step* (containerLength-1);
fields.each(function() {
var x = Math.round(width + radius * Math.cos(angle));
var y = Math.round(height + radius * Math.sin(angle));
$(this).css({
right: x + 'px',
top: y + 'px'
});
angle -= step;
});
}
var center = $('#center');
$(window).resize(function(height) {
$('#container').width($(window).height()*0.9)
$('#container').height($(window).height()*0.9)
var width = $('#container').width() * 0.4;
console.log("width",$('#container').width());
console.log("height",$('#container').height());
var radius = width/2;
width += 'px';
radius += 'px';
center.css({
width: width, height: width,
'-moz-border-radius' : radius,
'-webkit-border-radius' : radius,
'border-radius' : radius
});
createFields();
distributeFields();
// rest of your code for font-size setting etc..
});
$(window).resize();
$('input').change(function() {
createFields();
distributeFields();
});
答案 0 :(得分:0)
必须更改初始角度。
angle = -90*Math.PI/180; // (deg) * [Math.PI/180 == rad to deg]
//We have to provide values in radians, so we convert our degrees to radians
