我使用的是RedQueryBuilder版本0.5.0 http://0-5-0.redquerybuilder.appspot.com/用于构建Expression验证程序。 我想知道，如何验证输入的表达式？ RedQuery Builder 0.5.0的元数据支持Jquery支持的css和类添加。 请建议如何将css元数据添加到现有元数据中。
示例元数据如下：
meta : {
tables : [ {
"name" : "PERSON",
"label" : "Person",
"columns" : [ {
"name" : "NAME",
"label" : "Name",
"type" : "STRING",
"size" : 10
}, {
"name" : "DOB",
"label" : "Date of birth",
"type" : "DATE"
}, {
"name" : "SEX",
"label" : "Sex",
"type" : "STRING",
"editor" : "SELECT"
}, {
"name" : "CATEGORY",
"label" : "Category",
"type" : "REF",
} ],
fks : []
} ],
types : [ {
"name" : "STRING",
"editor" : "TEXT",
"operators" : [ {
"name" : "=",
"label" : "is",
"cardinality" : "ONE"
}, {
"name" : "<>",
"label" : "is not",
"cardinality" : "ONE"
}, {
"name" : "LIKE",
"label" : "like",
"cardinality" : "ONE"
}, {
"name" : "<",
"label" : "less than",
"cardinality" : "ONE"
}, {
"name" : ">",
"label" : "greater than",
"cardinality" : "ONE"
} ]
}, {
"name" : "DATE",
"editor" : "DATE",
"operators" : [ {
"name" : "=",
"label" : "is",
"cardinality" : "ONE"
}, {
"name" : "<>",
"label" : "is not",
"cardinality" : "ONE"
}, {
"name" : "<",
"label" : "before",
"cardinality" : "ONE"
}, {
"name" : ">",
"label" : "after",
"cardinality" : "ONE"
} ]
}, {
"name" : "REF",
"editor" : "SELECT",
"operators" : [ {
"name" : "IN",
"label" : "any of",
"cardinality" : "MULTI"
}]
} ]
},
