About the visibility problem of controls_html/css_WEB-ITnose

select control

temporary
fixed


1
2
3< ;/option>

Then I get the value from the database. When the page is displayed, when the value of sel1 is temporary, the control sel2 is hidden
When the value of sel1 When it is fixed, control sel2 is in the display state.
Please ask God

        $("#sel1").change(function () {            if ($(this).val() == "临时") {                $("#sel2").hide();            } else {                $("#sel2").show();            }        });

        $("#sel1").change(function () {            if ($(this).val() == "临时") {                $("#sel2").hide();            } else {                $("#sel2").show();            }        });

I know it can be written like this.
But I want to judge the value of sel1 taken out from the database when the page is loaded, and control the visibility of the sel2 control based on this value, not when the value of the sel1 control changes ----- --------Thank you

Then you can get the value of sel1 after the page is loaded
Java may be like this
window.onload=function(){
var sel1='${requestScope.name}';
if(sel1=='....'){
sel2.style.display='none';
}else{
. ...code
}
}

        $("#sel1").change(function () {            if ($(this).val() == "临时") {                $("#sel2").hide();            } else {                $("#sel2").show();            }        });

I don’t know what framework you are using. If it is mvc, get the value of sel1 from DB before return view(), and then stuff a viewBag or something like that. Go to the front desk and judge based on this. Personally I feel~~

The idea should be similar~~

The idea is It’s almost the same, but I just can’t turn my head around = =
