如何有一个字符串是这样的形式str = "&bbbLAA";
想得到"L"的话可以这样去实现：
//sDataStr = "&bbbLAA";
//sLeftQuote = ""&bbb";
//sRightQuote = "&AA";
调用这个方法将得到L字段。
function abCutString( sDataStr, sLeftQuote, sRightQuote)
{
var sReturnVal = '';
var nStartPos = sDataStr.indexOf(sLeftQuote) ;
if (nStartPos < 0) return sReturnVal;
nStartPos += sLeftQuote.length ;
if (nStartPos >=0 ) {
var sWorkStr = sDataStr.substring( nStartPos , sDataStr.length );
var nEndPos = sWorkStr.indexOf(sRightQuote) //- sRightQuote.length + 1;
if ( nEndPos >= 1 ) {
sReturnVal = sWorkStr.substring( 0 , nEndPos );
}
}
return sReturnVal ;
}
