关于设置 UI 不透明度量滑块的问题
Issue on Setting UI Slider For Opacity Amount
你能看一下 this jsfiddle 并告诉我如何使用滑块获取从 0
到 1
的值,例如 0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1
这是我的
$(function() {
$( "#slider" ).slider({
value:1,
min: 0,
max: 1,
step: 10,
slide: function( event, ui ) {
$( "#opacity" ).val( ui.value );
}
});
$( "#opacity" ).val( $( "#slider" ).slider( "value" ) );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<p>
<label for="amount">Opacity:</label>
<input type="text" id="opacity" readonly style="border:0; color:#f6931f; font-weight:bold;">
</p>
<div id="slider"></div>
你的步长值太大,试试:
$( "#slider" ).slider({
value:1,
min: 0,
max: 1,
step: 0.1,
slide: function( event, ui ) {
$( "#opacity" ).val( ui.value );
}
});
