Puppeteer 循環表行 - 在每一行上選擇下拉選項“選項“P”作為參數
[英]Puppeteer loop table rows - select dropdown option on each row "Option "P" for parameters
問題描述
我嘗試使用 Puppeteer 來遍歷表元素行。 表格最后一列中的每一行都有一個下拉列表。 我想為參數選擇選項“P”並獲取所有 href 鏈接並創建這些鏈接的數組....然后一一輸入以截取屏幕截圖。
這是我的表格元素...
我希望有人可以幫助我完成循環的步驟並單擊下拉列表以選擇一個選項 - 構建鏈接數組，然后單擊每個鏈接並拍攝快照。
謝謝你的幫助

我為來到這里的其他人找到了自己的問題解決方案。
下面的代碼正在查找名稱以“x”開頭的所有選擇標簽。
然后它獲取對象的長度 - 遍歷所有元素以從每個元素中提取選項 1 值！ 那正是我所需要的。
var sel;
const relevantValues = [];
for(var z=0; z<selects.length; z++){
sel = selects[z];
if(sel.name.indexOf('x') === 0){
relevantValues.push(sel.options[1].value);
};
};
下拉列表，其中包含每個選項的內容（ <select> ， <option> ）
[英]Dropdown List with content for each option (<select>,<option>)
使用 Puppeteer 從下拉菜單中選擇沒有值的特定選項
[英]Select an specific option from Dropdown Menu without values using Puppeteer
