Add a meter Image
ကၽြန္ေတာ္တုိ႕ အေနနဲ႕ <meter> tag ကို လက္ရိွ range value ကို ေဖာ္ျပတဲ့ ေနရာမွာ အသံုးျပဳႏိုင္ပါတယ္။
<meter>54 points</meter>ဆုိရင္ လက္ရိွ value မပါရိွတဲ့ အတြက္ ေအာက္ကလို သာ ေဖာ္ျပပါလိမ့္မယ္။
Figure 5-18
<meter value="38" min="0" max="100">38 points</meter>value က 38 ျဖစ္ျပီး အနိမ့္ဆံုးက 0 ။ အျမင့္ဆံုးက ၁၀၀ ျဖစ္တယ္လုိ႕ ဆုိထားပါတယ္။
Figure 5-19
အဲဒီ code ကို low , high , optimum attribute ေတြ ထည့္သြင္းပါမယ္။ အနိမ့္ ၊ အျမင့္ ႏွင့္ အျမင့္ဆံုးေပ့ါ။ အနီ ၊ အဝါ ႏွင့္ အစိမ္းေရာင္ေတြ နဲ႕ ေဖာ္ျပပါလိမ့္မယ္။
Figure 5-20
Loading အေနနဲ႕ ျပခ်င္တာ ။ progress အေနနဲ႕ အလုပ္လုပ္ေစခ်င္ရင္ေတာ့ meter အစား progress tag ကို သံုးသင့္ပါတယ္။
$0 <progress value="850" max="1000">$850</progress> $1000အဲဒီ code က chrome မွာ ဆုိရင္ ေအာက္ကလို ျမင္ရပါမယ္။
