我正在使用频谱API,我无法弄清楚如何使用颜色选择器工具更改基本文本。我可以看到基本示例可以返回颜色的十六进制值,但是如何使用该返回值来更改HTML或CSS中的文本颜色呢?
这是我正在尝试做的jsfiddle链接

// HTML
<h2>Basic Usage</h2>
<input type='text' class="basic"/>
<em id='basic-log'></em>
<h2>Full Example</h2>
<input type='text' id="full"/>
<p id="basic">
text basic
</p>
<p id="full">
text full
</p>
// CSS
.full-spectrum .sp-palette {
max-width: 200px;
}
#basic{
}
#full{
}
// JQuery的
$(".basic").spectrum({
color: "#f00",
change: function(color) {
$("#basic-log").text("change called: " + color.toHexString());
}
});
$("#full").spectrum({
color: "#ECC",
showInput: true,
className: "full-spectrum",
showInitial: true,
showPalette: true,
showSelectionPalette: true,
maxSelectionSize: 10,
preferredFormat: "hex",
localStorageKey: "spectrum.demo",
move: function (color) {
},
show: function () {
},
beforeShow: function () {

change: function() {

常规 DOM 方式:document.getElementById("id").style.color = "#0f0f0f";
应用于您的演示:
$(".basic").spectrum({
color: "#f00",
change: function(color) {
$("#basic-log").text("change called: " + color.toHexString());
document.getElementById("basic").style.color = color.toHexString();
}
});
jQuery 的方式:$(element).css('color', '#0f0f0f');
应用于您的演示:
$(".basic").spectrum({
color: "#f00",
change: function(color) {
$("#basic-log").text("change called: " + color.toHexString());
$(basic).css('color', color.toHexString());
}
});
