js代码

　　

/*
* 获取UTC格式的字符串,参数必须是
*/
var solrDateFormat = function (o){
var date;
if(typeof o == 'string'){
date = new Date(o);
}else if(o instanceof Date){
date = o;
}else{
return '';
}
return date.getUTCFullYear() + '-' + (date.getUTCMonth() + 1) + '-'
+ date.getUTCDate() + 'T' + date.getUTCHours() + ':'
+ date.getUTCMinutes() + ':' + date.getUTCSeconds() + 'Z';
};

/*
* 转义字符查询
*/
var escapeQueryChars = function (q){
var result = '';
//如果字符串q 不为空(null,未定义,空)
if (q !== null && q !== undefined && q !== '' && q !=="") {
for(var i=0;i < q.length;i++){
var c = q.charAt(i);
if (c == '\\' || c == '+' || c == '-' || c == '!'  || c == '(' || c == ')' || c == ':'
|| c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c == '}' || c == '~'
|| c == '*' || c == '?' || c == '|' || c == '&'  || c == ';' || c == '/'
|| c == ' ') {
result = result+ '\\';
}
result = result+ c;
}
}else{
return "*:*";
}
return result;
};
