在Inspections#show的上下文中,我使用will_paginate遍歷項目集合,當客戶點擊will_paginate的頁面對象列表中的另一個頁面的鏈接時,它的Score將被髮布到數據庫。因爲will_paginate不POST很好地工作,我用我已經在這裏摘錄使用this post答案:爲什麼我的JS腳本不是在Rails4中的form.submit()?

所以對於JS,每個作品的每一行。第一個收益正確。我通過交換Alert()的代碼來測試這一點,以確保preventDefault正常工作。第二個產生變量的正確值,如console.log()所示。第三個作品是因爲在控制檯中,我在瀏覽器中看到了代碼。提交作品和重定向發生,除了:頁面參數不傳遞。
單擊will_paginate鏈接將在右側執行GET:page參數。在服務器日誌中沒有POST操作。就好像preventDefault()沒有被識別一樣。爲此,當我查看Chrome的來源並點擊檢查時,我會看到結果:「1?page = 2」。也許Chrome不喜歡我的JS?我確定這是我忽略的一些愚蠢的東西。
我試圖刪除form_for的ajax調用,但沒有什麼不同。這篇文章的作品,但沒有找到頁面參數,因此它默認爲1.
爲什麼不是表單submit()發生,爲什麼不傳遞頁面參數?感謝名單,SAM
