1）jquery.tableGen.js，这段js的作用是产生一个表格，表格中显示数字和雷区，调用的方法很简单，如下:
var options ={
rows:5,
cols:5,
percent:0.1
};
$("table").tableGen(options);
思路是：根据table的单元格的数目随机产生percent的雷，并填充td。然后遍历所有的td，查找周围雷的个数来填充单元格的数字
[javascript] view plain copy
var neigUp = new Array();
var neig = new Array();
var neigDw = new Array();
var cols,rows;
var table,tds;
var colors =["black","blue","red","orange","yellow","green","black","black"]; var mineNum ;
function($){
var randoms = function(max,percent){
// General digital between 0 and max num times
if(!max)max =100;
if(!percent) percent =0.1;
num = max*percent;
var i=0;
var arr = new Array();
while(i<num) arr[i++]=Math.floor(Math.random()*max);
return arr;
}
$.fn.tableGen = function(options){
var setting = $.extend({
rows:10,
cols:10,
percent:0.1
},options || {}
);
rows = setting.rows;
cols = setting.cols;
neigUp = [-(cols+1),-cols,-(cols-1)];
neig =[-1,1];
neigDw =[cols-1,cols,cols+1];
var str = "";
for(var j=0;j<setting.rows;j++){
str+="<tr>";
for(var i=0;i<setting.cols;i++){
str+="<td>"+i+"</td>";
}
str+="</tr>";
}
this.empty();
this.append(str);
$("td",this).addClass("org"); // orginal color
//fill
var arr = randoms(setting.rows*setting.cols,setting.percent);
tds = $("td",this);
mineNum = arr.length;
for(var i=0;i<arr.length;i++){
$(tds[arr[i]]).addClass("mine").html("<span>"+"*"+"</span>").find("span").css("opacity",0);
}
// add tips number to regular cells
var $this =this;
tds.each(function(i){
if($(this).text() == "*") return;
var cnt = 0;
var seq = i;
for(var i=0;i<neig.length;i++){
var p = neig[i]+seq;
if(tds[p]&&Math.floor(p/cols) == Math.floor(seq/cols) && $(tds[p]).text() == "*") cnt++;
}
for(var i=0;i<neigUp.length;i++){
var p = neigUp[i]+seq;
if(tds[p]&&Math.floor(p/cols)+1 == Math.floor(seq/cols )&& $(tds[p]).text() == "*") cnt++;
}
for(var i=0;i<neigDw.length;i++){
var p = neigDw[i]+seq;
if(tds[p]&&Math.floor(p/cols)-1 == Math.floor(seq/cols) && $(tds[p]).text() == "*") cnt++;
}
if(!cnt) { cnt = ""; colors[""]="";}
$(this).html("<span>"+cnt+"</span>").css("color",colors[cnt]).find("span").css("opacity",0);
});
tds.addClass("mark");
} // tableGen Fn end
)(jQuery);
2）jquery.fill.js。这段代码的作用是定义点击事件，每次点击根据点击的内容来显示周围的区域或者提示成功失败
[javascript] view plain copy
(function($){
neig =[-1,1];
neigDw =[cols];
neigUp = [-cols];
var recover =function(td,table){
if(!td) return;
if(!td.attr) td = $(td);
if(!td.hasClass("mark")){
return;
}
if(td.text() == ""){
td.removeClass("mark").find("span").css("opacity",1);
}
else if(td.text() !="*"){
td.removeClass("mark").find("span").css("opacity",1);
return;
}
else if(td.text() == "*"){
return;
}
var seq = td.index("td",table);
tds = table.filter("td");
/*----------------------------*/
for(var i=0;i<neig.length;i++){
var p = neig[i]+seq;
if(tds[p]&&Math.floor(p/cols) == Math.floor(seq/cols) && $(tds[p]).text() != "*") {
recover($(tds[p]),table);
}
}
for(var i=0;i<neigUp.length;i++){
var p = neigUp[i]+seq;
if(tds[p]&&Math.floor(p/cols)+1 == Math.floor(seq/cols )&& $(tds[p]).text() != "*") {
recover($(tds[p]),table);
}
}
for(var i=0;i<neigDw.length;i++){
var p = neigDw[i]+seq;
if(tds[p]&&Math.floor(p/cols)-1 == Math.floor(seq/cols) && $(tds[p]).text() != "*") {
recover($(tds[p]),table);
}
}
}
$.fn.fill = function(){
table = $(this);
tds =$("td",table);
var mineCnt = 0;
tds.click(function(event){
if($(this).text() != "*"){
if(event.altKey){
tds.removeClass("mark").find("span").css("opacity",1);
var rs = confirm("No Bomb here !Bad Luck,Try Again?");
if(rs){
table.tableGen(options).fill();
}
return;
}
}
if($(this).text() == "*"){
$(this).removeClass("mark").find("span").css("opacity",1);
var event = event || window.event;
if(event.altKey){
mineCnt++;
if(mineCnt == mineNum){
var rs = confirm("congratulations!Try Again?");
if(rs){
table.tableGen(options).fill();
}
return;
}
return;
}
// Game over
tds.removeClass("mark").find("span").css("opacity",1);
var rs = confirm("Bomb!Bad Luck,Try Again?");
if(rs){
table.tableGen(options);
table.fill();
}
}
else if($(this).text() !="*" && $(this).text() !=""){
$(this).removeClass("mark").find("span").css("opacity",1);
}
else
recover($(this),tds);
});
};
})(jQuery);
