如何使用光谱颜色选择器隐藏某些颜色答案

【问题描述】：

我不熟悉使用 Spectrum 的颜色选择器。因此，我查看了光谱颜色选择器必须提供的所有功能，但我找不到在颜色选择器中隐藏某些颜色以使用户无法选择它们的方法。

例如，所有浅色：#FFFFFF、#F5F5F5、#FFFAFA、#F0FFF0、#F5FFFA、#F0FFFF、#F0F8FF、#F8F8FF、#FFF5E、#F5F5DC、#FDF5E6、#FFFAF0、#FFFFF0、#FAEBD7 , #FAF0E6, #FFF0F5 不应该在颜色选择器中可用。

有什么办法可以做到吗？

【解决方案1】：

您必须创建一个带有限制颜色 hax 的数组列表。那么你应该使用change 方法来处理。和 jquery $.inArray() 函数确定受限颜色。

例如

var banColor = ['#ffffff','#000000','#F0FFF0', '#F5FFFA', '#F0FFFF', '#F0F8FF', '#F8F8FF', '#FFF5E', '#F5F5DC', '#FDF5E6', '#FFFAF0', '#FFFFF0', '#FAEBD7', '#FAF0E6', '#FFF0F5'];

$(".example").spectrum({
    color: "#f00",
    change: function(color) {
        if( $.inArray( color.toHexString(), banColor ) >= 0 ){
            $("#basic-log").text("change called: " + color.toHexString() +' Is Not Allowed');
            // Reset your palate
        }
    }
});

您无法删除颜色选择器中的颜色，但您可以在调色板中显示用户可以使用的有限数量的颜色，而不包括用户无法选择的颜色。

$("#togglePaletteOnly").spectrum({
    showPaletteOnly: true,
    togglePaletteOnly: true,
    togglePaletteMoreText: 'more',
    togglePaletteLessText: 'less',
    color: 'blanchedalmond',
    palette: [
        ["#000","#444","#666","#999","#ccc","#eee","#f3f3f3","#fff"],
        ["#f00","#f90","#ff0","#0f0","#0ff","#00f","#90f","#f0f"],
        ["#f4cccc","#fce5cd","#fff2cc","#d9ead3","#d0e0e3","#cfe2f3","#d9d2e9","#ead1dc"],
        ["#ea9999","#f9cb9c","#ffe599","#b6d7a8","#a2c4c9","#9fc5e8","#b4a7d6","#d5a6bd"],
        ["#e06666","#f6b26b","#ffd966","#93c47d","#76a5af","#6fa8dc","#8e7cc3","#c27ba0"],
        ["#c00","#e69138","#f1c232","#6aa84f","#45818e","#3d85c6","#674ea7","#a64d79"],
        ["#900","#b45f06","#bf9000","#38761d","#134f5c","#0b5394","#351c75","#741b47"],
        ["#600","#783f04","#7f6000","#274e13","#0c343d","#073763","#20124d","#4c1130"]
    ]
});

希望对你有帮助。
