使用 ng-style 作为背景渐变时出现 AngularJS 语法错误,并且如果我仅使用 style 标签,则无法在 IE 11 中工作。需要帮助
<div class="test-data" ng-style="{{statusStyle}}"></div>
var empty = 100 - status.test;
$scope.statusStyle = {'background': 'linear-gradient(#f2f2f2 ' + empty + '%, ' + color + ' ' + empty + '%)'};

最佳答案
尝试此代码更改
<div class="test-data" style="background: {{statusStyle}}"></div>
var empty = 100 - status.test;
$scope.statusStyle = 'linear-gradient(#f2f2f2, ' + color + ' ' + empty + '%)';
此更改使 {{statusSyle}} Angular 表达式计算为 JavaScript 字符串,而不是使用 { field : "value", ...} 设置的 JavaScript 对象。 AngularJS 语法错误可能是由于尝试将 $scope.styleStatus 对象写入表达式而导致的。
另一个变化是在线性渐变的色标中仅包含 1%。仅在第二个色标中使用 %。
大多数浏览器支持 CSS3 线性渐变已有一段时间了。
一般语法:
背景:线性渐变(方向,color-stop1,color-stop2,...);
将两个颜色停止点设置为相同的%时,您将不会获得线性渐变,而是会在使用第一种颜色输入的%值处获得颜色中断,并且通常浏览器会忽略第二种颜色上的%。
在浏览器中使用下面的示例代码来测试一些线性渐变。
HTML 代码
<body>
<div id="grad"></div>
To create a linear gradient you must define at least two color stops. Color stops are the colors you want to render smooth transitions among. You can also set a starting point and a direction (or an angle) along with the gradient effect.
<br>
Syntax:<br>
background: linear-gradient(direction, color-stop1, color-stop2, ...);
</body>
样式
#grad {
width: 100%;
height: 620px;
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(red, yellow 90%);
/* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red, yellow 90%);
/* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red, yellow 90%);
/ For Firefox 3.6 to 15 */
background: linear-gradient(red, yellow 90%);
/* Standard syntax */
}
