一、引入
import katex from 'katex';
import 'katex/dist/katex.css';
二、使用
<span class="mathHtml">\omega \varphi \xi \mu </span>
this.$nextTick(() => {
var math = document.getElementsByClassName('mathHtml');
for (var i = 0; i < math.length; i++) {
katex.render(math[i].innerText, math[i]);
}
});
function katexRender(dom = 'mathHtml') {
this.$nextTick(() => {
var math = document.getElementsByClassName(dom);
for (var i = 0; i < math.length; i++) {
katex.render(math[i].innerText, math[i]);
// var html = katex.renderToString(math[i].innerText, {
// throwOnError: false
// });
// console.log('html', html);
}
});
}
