使用htmldriver在Selenium Java中单击没有ID，标签等的链接

Question

How can i click the below? i Have tried using the XPath but no cigar!

My attempt:

WebElement submit = driver.findElement(By.xpath("/html/body/form/table[7]/tbody/tr[2]/td[1]/a"));
submit.click();

This is the HTML:

<a href="#" onclick="return mysubit('save', window.document.jobform);">
    <img src="/shared/images/template_APC/order/submit.gif" width="90" height="17" border="0" alt="Submit Booking">
</a>

Answer 1

You haven't said what the error being shown is but it could be that td[1] contains multiple a elements, or that something in the xpath you defined has changed. If you specifically want td1 , specify in the xpath what you want from it (ie, it could be //td[@name='cell1'] ) etc. Hard coding specific indexes in xpath, I've found, is often prone to error.

For the xpath I'd go with: //table[@id/class/name='xxx']//td[@id/class/name='xxx']/a[contains(@onclick,'mysubmit')] and click that. (I assume your method for submission is mysubmit and not mysubit as you've written).

Using hard coded XPaths are prone to problems... depending on the browser they are run in, how often the structure of the HTML changes, etc. What I typically do in a situation like this is to look at the predecessors from the desired A tag. Hopefully you can find one with an ID or class , etc. that can serve as a start. You likely won't be this lucky but you hopefully will get the idea...

<div id="home">
    <a href="#" onclick="return mysubit('save', window.document.jobform);">
        <img src="/shared/images/template_APC/order/submit.gif" width="90" height="17" border="0" alt="Submit Booking">
    </a>
</div>

In this case you can use a CSS Selector to quickly get the A you want.

driver.findElement(By.cssSelector("#home > a")).click();

The CSS Selector, "#home > a" , means starting with the element with an ID of "home" ( #home ) find immediate children ( > ) that are a tags.
