- 调用示例
<pre class="hljs language-javascript" style="overflow-wrap: break-word; margin-top: 0px !important; margin-right: 0px; margin-bottom: 1.25rem; margin-left: 0px; padding: 1rem; text-decoration: none; font-style: normal; box-sizing: border-box; font-family: SFMono-Regular, Menlo, Monaco, Consolas, "Liberation Mono", "Courier New", monospace; font-size: 14px; overflow: auto; color: rgb(36, 41, 46); background: rgb(233, 236, 239); max-height: 35rem; line-height: 1.5;">const style = {
position: 'absolute',
top: 0,
right: 0,
bottom: 0,
left: 0,
};
function OpenWeapp({ originId, pagePath }) {
return (
<wx-open-launch-weapp username={originId} path={pagePath} style={style}>
<script type="text/wxtag-template"> <div style={style} /> </script>
</wx-open-launch-weapp>
);
}
// 使用方式
<div style={{ position: 'relative' }}>

<OpenWeapp originId="gh_xxxxxxxx" pagePath="pages/home/index?user=123&action=abc" />
</div>
</pre>
为什么给div添加position: relative呢？
由于wx-open-launch-weapp设置样式比较困难，故放弃设置样式，将wx-open-launch-weapp作为一个透明的占位元素，撑满父元素，也能达到预期的功能。
