fnErrorFlash(args) - 错误闪烁背景色提示.jq

[javascript]代码库

目标：像新浪微博内容输入框的效果

特别注意：使用setTime调用函数的时候，字符串要加上引号，数字不用加；因为没有给字符串加引号导致：

Uncaught SyntaxError: Unexpected token ILLEGAL    没有捕获的语法错误：意外的标记是非法的


function fnErrorFlash(selector, times, errorcolor, normalcolor, delaytime) {
    $(selector).css("background-color", errorcolor);
    times = times - 1;
    setTimeout("normalFlash('" + selector + "'," + times + ",'" + errorcolor + "','" + normalcolor + "'," + delaytime + ")", delaytime);
}
function normalFlash(selector, times, errorcolor, normalcolor, delaytime) {
    $(selector).css("background-color", normalcolor);
    if (times < 0) {
        return;
    }
    times = times - 1;
    setTimeout("fnErrorFlash('" + selector + "'," + times + ",'" + errorcolor + "','" + normalcolor + "'," + delaytime + ")", delaytime);
