调用接口但是如果将返回数据的css写在文件中
是不会生效的这时候应该如何
我们先将写在文件中的cssconst一个css参数将css放进去
const css = `.taTitle {
display: block;
border-top: 2px solid rgba(250, 250, 250, 0.36);
height: 35px;
line-height: 35px;
font-family: PingFangSC-Regular, '微软雅黑';
font-size: 16px;
text-align: center;
margin-bottom: 14px;
}
.articleRecommendation_con{
clear: both;
margin: 6px 0px;
overflow: hidden;
}
.articleRecommendation_con a:nth-child(1) {
float: left;
width: 28%;
height: 66px;
padding: 5px 0px;
}
a:link {
text-decoration: none;
color: #ffffff;
}
.articleRecommendation_con a:nth-child(1) img {
width: 92%;
}
.articleRecommendation_con img {
overflow-clip-margin: content-box;
overflow: clip;
}
.articleRecommendation_con a:nth-child(2) {
display: block;
width: 72%;
float: left;
}
.articleRecommendation_con_right p:nth-child(1) {
display: none;
}
.articleRecommendation_con p {
display: block;
margin-block-start: 1em;
margin-block-end: 1em;
margin-inline-start: 0px;
margin-inline-end: 0px;
}
.articleRecommendation_con_right p:nth-child(2) {
margin: 0px;
line-height: 22px;
word-wrap: break-word;
text-align: left;
font-size: 14px;
}
.articleRecommendation_con_right p:nth-child(3) {
margin: 0px;
line-height: 20px;
word-wrap: break-word;
text-align: left;
}
.articleRecommendation_con_right p:nth-child(3) span:nth-child(1) {
display: none;
}
.articleRecommendation_con_right p:nth-child(3) span:nth-child(2) {
color: #ececec;
line-height: 20px;
font-family: PingFangSC-Regular, '微软雅黑';
font-size: 12px;
text-align: left;
}`
const sheet = new CSSStyleSheet();
sheet.replaceSync(css);
document.adoptedStyleSheets = [sheet];然后就css生效了
