次のコードでは、「ヘッダー」div の色を対応する JSON の色に変更する必要があります。使用:
$("#dropdown").change(function() {
$("#header").css("background-color", $(this).val());
}).change();
JSON で 16 進数の色を取得して div に適用するにはどうすればよいですか?
HTML
<div id="header">Header</div>
<select id="dropdown">
<option value="">Select</option>
</select>
<a href="#" id="fetch">Fetch JSON</a>
JSON
var json = {
"dropdown": [
{
"optionText": "Budget Starter",
"headerText": "Work 1-on-1 with your expert to build new spending habits (and break some old ones). Get on a real, sustainable budget that fits your lifestyle.",
"color": "#59c5c7"
},
{
"optionText": "5 Year Planner",
"headerText": "Declare what you want - freedom from debt, security for your family, or an amazing trip. Your expert will build you a custom plan to help you get there.",
"color": "#009cd0"
},
{
"optionText": "Portfolio Builder",
"headerText": "Start training for the world's hardest game: investing. Your expert will help you grow into a disciplined and balanced portfolio manager.",
"color": "#39ad74"
}
]
};
jQuery
$('#fetch').click(function() {
$.post('/echo/json/', {json: JSON.stringify(json)}, function(data) {
$.each(data.dropdown, function(i, v) {
$('#dropdown').append('<option value="' + v.optionText + '">' + v.optionText +
'</option>');
});
});
});
//change color of header container based on dropdown selection
$("#dropdown").change(function() {
$("#header").css("background-color", $(this).val());
}).change();
