無法點擊使用硒網絡驅動程序

Question

複選框，我試圖用objectIdentifierValue

id - cntMain_chkPrimaryInvestigator_A 
name - ctl00$cntMain$chkPrimaryInvestigator_A  
xpath - //input[@id='cntMain_chkPrimaryInvestigator_A'] 
xpath - //span/div/input 

但都不是工作，我收到錯誤，如「網頁上找不到這樣的元素」。

Going through the examples given for all the other related questions I could not find a proper solution that works in a concise way that allows me to check a checkbox with a few lines of code or method. 

如何使用webdriver腳本選擇此複選框？

任何幫助，將不勝感激。

這裏是HTML代碼如下：

<div class="input-heading nonresearchHide"> 
    <span id="cntMain_lbl_Primary_investigator">Primary investigator</span> 
    </div> 
    <div class="nonresearchHide"> 
    <div class="icon-info" data-content='Please add the Primary Investigator that was responsible for the research if they are not already added to this activity' data-placement="top" data-toggle="popover" data-container="body" data-trigger="hover"></div> 
    <p class="defaultP"> 
    <div class="RadAjaxPanel" id="ctl00_ctl00_cntMain_chkPrimaryInvestigator_APanel"> 
    <span class="check_box"> 
    <input id="cntMain_chkPrimaryInvestigator_A" type="checkbox" name="ctl00$cntMain$chkPrimaryInvestigator_A" tabindex="7" /> 
    </span> 
    </div> 
    </p> 
    </div> 

Answer 1

具有u試過這樣：

driver.findElement(By.id("cntMain_chkPrimaryInvestigator_A")).click(); 

如果這沒有幫助，請展示你的代碼的細節。

Answer 2

使用代碼：

driver.findElement(By.xpath("//span[@class='check_box]")).click(); 

嘗試用點擊跨度它是特定的輸入
