今天工作中遇到的问题有2个，
1，js传递中文参数到一般处理程序，字符的编码转换，js 使用escape 方法
var searchs = $("#txtSearch").val(); //list页面搜索框
if (searchs != "请输入小区名称或地址...") {
var search = escape(searchs);
}
else {
search = "";
}
一般处理程序端对代码解密
1 if (!string.IsNullOrEmpty(keyword)) 2 { 3 string key = context.Server.UrlDecode(keyword); 4 query = query.Where(w => w.SQ_CODE.Contains(key) || w.HOUSE_TITLE.Contains(key) || w.ESTATE_NAME.Contains(key)); 5 6 }
2，lambam 表达式里面的多条件查询，其实很简单，只是一开始没有看懂
EFModel.ChlWebEntities ent = new EFModel.ChlWebEntities();
//EF 多条件跨表 查询
//List<EFModel.trm_f_house> zu_list = null;
//为什么走到这里会报错
var query = ent.trm_f_house.AsQueryable<EFModel.trm_f_house>();
query=query.Where(w => w.HOUSE_TYPE == "0" && w.STATUS == "A" );
int totalCount = 0;
if (region != "-1")
{
query = query.Where(w => w.AREA_CODE == region);
}
if (price != "-1")
{
string[] strpri = price.Split(‘,‘);
double aaa = Convert.ToDouble(strpri[0]);
double bbb = Convert.ToDouble(strpri[1]);
if (aaa == 0.0)
{
query = query.Where(w => w.SELL_PRI <= bbb);
}
if (bbb == 500.0)
{
query = query.Where(w => w.SELL_PRI >= aaa);
}
query = query.Where(w => w.SELL_PRI >= aaa && w.SELL_PRI <= bbb);
}
3.限制文本框只能输入数字
1 onkeyup="if(this.value.length==1){this.value=this.value.replace(/[^1-9]/g,‘‘)}else{this.value=this.value.replace(/\D/g,‘‘)}" 2 onafterpaste="if(this.value.length==1){this.value=this.value.replace(/[^1-9]/g,‘‘)}else{this.value=this.value.replace(/\D/g,‘‘)}"
4，lambamd表达式排序，用iqueryable方式的排序 目前还没有解决。
