一个奇怪的JS函数 今天在分析一个jQuery插件源码的时候,发现了一个奇怪的函数。 这个函数的目的是为数字补零,如传入7,输出07,传入12输出12。由于是对时间补零,只截取后两位。 //add leading zerosvarpad =function(x){return(1e15+""+x).slice(-2)}; 首先1e15是什么意思? 也不是十六进制表示法。 不管...

0 : p; // Create version of divisor with leading zero. bz.unshift(0); // Add zeros to make remainder as long as divisor. for (; rl++ < bl;) r.push(0); do { // n is how many times the divisor goes into current remainder. for (n = 0; n < 10; n++) { // Compare ...

To do this, add the option resources: "usable" as described below. (You'll likely also want to set the url option, for the reasons discussed there.) Event handler attributes, like , are also governed by this setting; they will not function unless runScripts is set to "dangerously". (H...
