python selemium driver.execute_script()

March 27, 2022

I want to cancel all checkbox one time.
Use element.click() is ugly but it can work like this

allcan=driver.find_elements(By.XPATH,'//*[@type="checkbox"]')
for i in allcan:
    i.click()

So I try to use driver.execute_script() like this

allcan = 'var index = form1.no.value; \
            for (i=1;i<=index;i++){ \
                var rchk = document.getElementsByName("del_Y"+i)[0] \
                rchk.checked = false \
                ;}'
driver.execute_script(allcan)

That JavaScript can work in chrome console,but in python it show me

JavascriptException: Message: javascript error: Unexpected identifier
(Session info: chrome=99.0.4844.82)

I don’t know why please help me.

>Solution :

You need to end this statement with semicolon.

var rchk = document.getElementsByName("del_Y"+i)[0];

This will get rid of SyntaxError, but as @Peterrabbit mentioned in the comment you need to pay attension to i and form1 as those variables are not defined. So most likely you will encounter with Reference Error.
