javascript - 如何使用 jquery 应用复杂的生成样式？

Question

假设我们生成了这样的字符串:

    background:#6356ff;
background:url(data:image/svg+xml;
base64,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);
background:linear-gradient(top,#6356ff 0%,#75b6ff 100%);
filter:progid:DXImageTransform.Microsoft.gradient( startColorstr='#6356ff',endColorstr='#75b6ff',GradientType=0 );

现在我们要将这种复杂的样式应用到我们的文档 html 和正文中。如何使用 jQuery 执行此类操作？

Answer 1

添加它

$('#box').attr('style',str);

或者可以使用以下代码片段附加到现有样式

$('#box').attr('style',$('#box').attr('style')+str);
