实现SELECT的全选，反选，AB选的JAVASCRIPT代码

$(".btn-select-all").click(function(){
var deploypool_id =  $(this).attr("deploypool_id")
var code_Values = document.getElementsByName("check-server" + deploypool_id);
for(i = 0;i < code_Values.length;i++){
if(code_Values[i].type == "checkbox"){
code_Values[i].checked = true;
}
}
});

$(".btn-select-reverse").click(function(){
var deploypool_id =  $(this).attr("deploypool_id")
var code_Values = document.getElementsByName("check-server" + deploypool_id);
for(i = 0;i < code_Values.length;i++){
if(code_Values[i].type == "checkbox"){
code_Values[i].checked = false;
}
}
});

$(".btn-select-half").click(function(){
var deploypool_id =  $(this).attr("deploypool_id")
var code_Values = document.getElementsByName("check-server" + deploypool_id);
for(i = 0;i < code_Values.length;i++){
if (i % 2 == 0){
if(code_Values[i].type == "checkbox"){
code_Values[i].checked = true;
}
}
}
});
