Splinter: How to pass argument to execute_script?

I need to execute a javascript function on the page, by passing it an array of strings. I want to avoid having to call browser.execute_script number of times.

list_of_strings = ['a','b','c']

#js code runs through all the strings
result = browser.execute_script("function findTexts(textList){//code here}", list_of_strings)
Solution

  • Dump python list to JSON and use string formatting:

    import json

json_array = json.dumps(list_of_strings)
result = browser.execute_script("function findTexts(%s){//code here}" % json_array)

    Here's what js code does it produce:

    >>> import json
>>> list_of_strings = ['a','b','c']
>>> json_array = json.dumps(list_of_strings)
>>> "function findTexts(%s){//code here}" % json_array
'function findTexts(["a", "b", "c"]){//code here}'
