JQuery implementation method of passing parameters when binding events_jquery

For example, if I want to pass the current text box as a parameter to the function represented by functionName in $(":text").bind("keyup",funcionName);, how should I write it? I tried $(":text").bind("keyup",functionName(this)); This is wrong!

1. Using this directly in functionName is to refer to the element itself of the trigger time Quote, if you need functionName to have more parameters, you can use it like this:

2.$(":text").bind("keyup",function(){
funcionName(arg1,arg2 ,arg3,arg4);
});

3. If there is a parameter with event name, you can pass it
$(:text").bind("keyup", function(event) {
event = event || window.event;
var target = event.target; //This is the control that triggers the event
});
