$(oFind).bind('click',function(){ var oKeyword = $('.locating').val(); if( oKeyword != '' ){ $.ajax({ type:"post", async:true, url: "{:U('Reply/index')}", data:{keyword:oKeyword}, success:function(){ $(oZs).fadeOut("fast"); $(oCx).fadeIn("fast"); } }); } });

oFind is a button. After binding a click event to it, send an ajax request to the background and check the console that everything is normal. There are no errors in the parameters and URL.

But it just can’t print out ddd? Can you help me find out what’s wrong?

Sister, you don’t have a console, how can you print? success:function(){

$(oZs).fadeOut("fast"); $(oCx).fadeIn("fast"); } 改成 success:function(data){ console.log(data); $(oZs).fadeOut("fast"); $(oCx).fadeIn("fast"); }

    Ajax is not used like this. You pass the value, but if you echo something in the index, it cannot be seen on the other side.
    You set up a success callback and receive data processing here.
    I prefer json For transmission, if you use json, you can echo json_encode your data in the controller
