1、如果是通过URL传递：----需要编码两次

var searchText = this.searchText();

searchText = encodeURI(searchText);

searchText = encodeURI(searchText);

$.ajax({

type: 'GET',

url: $ctx + this.pageUrl + pageIndex + "&searchText=" + searchText,

data: '',

contentType: 'text/json,charset=utf-8',

dataType: 'json',

success: function(data) {

}

})

},

后台通过：

String queryCon = request.getParameter("searchText");

if(queryCon != null && queryCon != ""){

queryCon=URLDecoder.decode(queryCon,"utf-8");

}

反编译一下就可以获取到传递的中文~~

2、  直接通过ajax数据传递：只需编译一次~

var searchText = this.searchText();

searchText = encodeURI(searchText);

$.ajax({

type: 'GET',

url: $ctx + this.pageUrl + pageIndex ,

data: {search：searchText },

contentType: 'text/json,charset=utf-8',

dataType: 'json',

success: function(data) {

}

})

},

后台直接获取到传递的值，需要解码一次：

String queryCon = search;

if(queryCon != null && queryCon != ""){

queryCon=URLDecoder.decode(queryCon,"utf-8");

}
