运行下面的量角器脚本时
let resultantArr = [];
resultantArr = await browser.executeScript("var elements = document.querySelectorAll('ul[class=\'wbs-droplist-container\'][id*=\'droplist\'] li[class=\'wbs-droplist-item\'][id*=\'droplistitem\']') \
var arr = []; \
for (var i = 0; i < elements.length; i++) { \
arr.push(elements[i].innerText); \
} \
return arr;")
return resultantArr;
我在参数列表错误后出现 Failed: javascript error: missing )。请帮我解决这个问题。
