Js将带下划线的字符串改为驼峰命名

转换之前务必全转为小写

var fieldName = field.eFieldName.toLowerCase();

调用方法

var newFieldName = fieldTrans(fieldName);

方法

function fieldTrans(field){
    var resultField = field;
    if(field!=null){        
        var splitIndex = field.indexOf("_");
        if(splitIndex>-1){
            var beforeLetter = field.substring(0,splitIndex);
            var firstLetter = field.substring(splitIndex+1,splitIndex+2);
            var afterLetter = field.substring(splitIndex+2,field.length);
            var fLetter = firstLetter.toUpperCase();
            resultField = beforeLetter+fLetter+afterLetter;
            if(resultField.indexOf("_")>-1){
                resultField = fieldTrans(resultField);
            }else{
                return resultField;
            }
        }
    }   
    return resultField;
}
