The solution to the problem of garbled characters when using action on the page to pass parameters to the background

Use jquery ajax on the page

Copy the code code as follows:

function createQS(name){

var value = encodeURI(name);

var queryString = {key:value};

return queryString;

}

//Retrieve name method

function jiansuoByName(k,name){

if (name == '') {

alert("Please enter the search content");

return;

}

$.post(basePath+"/sysmgr/searchesAjax/searchesJsonPlugin!searchesNameByOMCByName.action", createQS(name),

function(data){

//alert(data.result+'/n'+k); // John

setLine_memoryFunction_A(data.result,k);

}, "json");

}

in background action

Copy the code code as follows:

import java.net.URLDecoder;

String _name = request.getParameter("key");

String name = URLDecoder.decode(_name,"utf-8");
