The string "PAYPALISHIRING" is written in a zigzag pattern on a given number of rows like this: (you may want to display this pattern in a fixed font for better legibility) P A H N A P L S I I G Y I R And then read line by line: "PAHNAPLSII

<script> b("); function b(id) { console.log("b函数的id:"+id); //var history = "<a href='#' onclick='a(" +id + ")'>历史</a>"; 错误代码这里id默认理解成数字类型,需要"",直接在前面添加会影响html结构报语法错误所以需要把"需要转义\" var h

转:http://blog.csdn.net/dxnn520/article/details/8267173 var定义的变量应该是字符串,有时没有经过类型转换而进行比较的话,小于十的话还可以,如果大于十就会出错 例: var hour_select_begin=$('#hour_select_begin option:selected').text(); var hour_select_end=$('#hour_select_end option:selected').text(); if(h
各种数字类型转换成字符串型 int i =8; String s =Integer.toString(i);// String g =String.valueOf(i); // 其中 value 为任意一种数字类型. 字符串型转换成各种数字类型: String s = "169"; byte b = Byte.parseByte( s ); short t = Short.parseShort( s ); int i = Integer.parseInt( s ); long l =

1.javascript的数组API Js代码 收藏代码 //定义数组 var pageIds = new Array(); pageIds.push('A'); 数组长度 pageIds.length; //shift:删除原数组第一项,并返回删除元素的值:如果数组为空则返回undefined var a = [1,2,3,4,5]; var b = a.shift(); //a:[2,3,4,5] b:1 //unshift:将参数添加到原数组开头,并返回数组的长度 var a = [1,2
