将 jscolor 类添加到引导导航栏

Question

我正在尝试让引导导航栏与 jscolor 一起使用，就像下面的按钮一样。

<script src="https://cdnjs.cloudflare.com/ajax/libs/jscolor/2.0.4/jscolor.min.js"></script>
<button
    class="jscolor {valueElement:null,value:'333'}"
    style="border:1px solid black">
    Color
</button>

这是我试图与 jscolor 连接的导航栏：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jscolor/2.0.4/jscolor.min.js"></script>
<script src="jscolor.js"></script>

<nav class="navbar navbar-inverse navbar-fixed-top jscolor {valueElement:null,value:'333'}">

Answer 1

希望这会有所帮助，z-index 是必需的，以便导航栏不会与颜色选择器重叠。

var nav = document.getElementById("navbar");
var navColor = document.getElementById("nav-color");

nav.addEventListener("click", function(){
	navColor.jscolor.show();
});

#navbar {
  z-index: 0;
  cursor: pointer;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jscolor/2.0.4/jscolor.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jscolor/2.0.4/jscolor.min.js"></script>

<input id="nav-color" class="jscolor {styleElement:'navbar',value:'333'}" type="hidden">
<nav id="navbar" class="navbar navbar-inverse navbar-fixed-top ">
</nav>

你可以添加一个按钮来改变颜色

a fiddle

function update(jscolor) {
 document.getElementById('navbar').style.backgroundColor = '#' + jscolor
}
