The following is the code to generate the dashboard and its password strength:

$(function(){
$('#submit').attr('disabled', true);
var g1 = new JustGage({
id: "complexity",
value: 0,
min: 0,
max: 100,
title: "密码强度提示",
titleFontColor: '#9d7540',
valueFontColor : '#CCCCCC',
label: "points",
levelColors: [
"#dfa65a",
"#926d3b",
"#584224"
]
});
$('input[placeholder]').placeholder();
$("#password").complexify({}, function(valid, complexity){
if(valid){
$('#submit').fadeIn();
}else{
$('#submit').fadeOut();
}
g1.refresh(Math.round(complexity));
});
$('#submit').click(function(){
$('#msgbox').html('welcome to gbtags.com');
});
});


In the above code, we use JustGage to generate the required dashboard. Please refer to the code for related options.

In the following code, we use complexify’s callback method to determine whether the password strength entered by the user meets the requirements:

$("#password").complexify({}, function(valid, complexity){
if(valid){
$('#submit').fadeIn();
}else{
$('#submit').fadeOut();
}
g1.refresh(Math.round(complexity));
});

If it matches, the registration button will be displayed, otherwise it will be hidden. Refresh the values ​​and colors of the dashboard at the same time.
