这使用Raphaeljs从数组中绘制一个弦:麻烦的setInterval和setTimeout的工作
function createChordStruct(key, string, shape) {
var string = string.toUpperCase();
var position = positions[string][key];
var struct = chord_shapes[shape];
return {
name: key + struct.name,
chord: struct.chord,
position: position,
position_text: struct.position_text,
bars: struct.bars
}
}
function createChordElement(chord_struct) {
var chordbox = $('<div>').addClass('chord');
var chordcanvas = $('<div>');
var chordname = $('<div>').addClass('chordname');
chordbox.append(chordcanvas);
chordbox.append(chordname);
chordname.append(chord_struct.name);
var paper = Raphael(chordcanvas[0], 150, 140);
var chord = new ChordBox(paper, 30, 30);
chord.setChord(
chord_struct.chord,
chord_struct.position,
chord_struct.bars,
chord_struct.position_text);
chord.draw();
return chordbox;
}
function createSectionElement(section_struct) {
var section = $('<div>').addClass('section');
var section_title = $('<div>').addClass('title');
var section_desc = $('<div>').addClass('description');
section.append(section_title);
section.append(section_desc);
section_title.append(section_struct.section);
section_desc.append(section_struct.description);
return section;
}
而这需要来自阵列创建的每个和弦,并把它们放在一个名为“chordscroller”新的div:
function c_i() {
var randomholder = 'id_' + (Math.floor(Math.random() * 100005) + 1);
var randomId = 'id_' + (Math.floor(Math.random() * 100005) + 1);
$(function() {
$('#sortable').append($('<li id ="' + randomholder + '" class="chordbox"><span id="i" class="scale">C - I</span><span id="' + randomId + '" class=" even scrollpane chordscroller"></span></li>').sortable("refresh"))
});
function c_one() {
var container = $("#" + randomId + "");
var column = null;
var column = _.shuffle(c_1);
for (var i = 0; i < column.length; ++i) {
var section_struct = column[i];
var section = createSectionElement(section_struct);
for (var j = 0; j < section_struct.chords.length; ++j) {
section.append(createChordElement(section_struct.chords[j]));
}
container.append(section);
}
}
$(function() { c_one() });
}
问题是它在同一时间绘制所有的和弦,它需要永远。我已经尝试了setTimeout和setInterval的所有组合,但我仍然遇到错误。
有人可以从这段代码告诉如何让一次一个而不是一次绘制一个和弦?
纠正我,如果我错了,但我既没有看到'setTimeout'也不'你已经发布代码的任何地方setInterval'。还有更多吗? –
我把它们拿出来,因为它们只是破坏东西。有*许多*变化。 – jthomasbailey
如果你可以用一个工作的例子建立一个jsbin环境会有所帮助。 – Jeemusu
