只能去除前面后面的空格,不能去除文本里面带的空格
js代码:
//**************************************************************** // Description: sInputString 为输入字符串,iType为类型,分别为 // 0 - 去除前后空格; 1 - 去前导空格; 2 - 去尾部空格 //**************************************************************** function cTrim(sInputString, iType) { var sTmpStr = ' '; var i = -1; if (iType == 0 || iType == 1) { while (sTmpStr == ' ') { ++i sTmpStr = sInputString.substr(i, 1); } sInputString = sInputString.substring(i); } if (iType == 0 || iType == 2) { sTmpStr = ' '; i = sInputString.length; while (sTmpStr == ' ') { --i; sTmpStr = sInputString.substr(i, 1); } sInputString = sInputString.substring(0, i + 1); } return sInputString; }
//去掉字符串所有空格
function jtrimstr(str) { var i=0; var j; var len=str.length; trimstr=""; while(i<len) { if(str.charAt(i)!=" ") { trimstr=trimstr+str.charAt(i); } i++; } return(trimstr); }
