How to read data from a webpage(on different domain) in javascript

i have created a online dictionary which takes word in url and displays it's meaning on web the url is something like this (i am not sharing the actual one)

http://some_domain/some_file.php?word=regret&search=Submit

the meaning of the word regret is displayed on webpage, i am simply using echo to print results (ex-echo Meaning[$word]) now i want to read these results from my other webpages but cannot figure out how to do it two things i want to know - can i read the results as i have mentioned above - or i need to make some changes in my some_file.php so that the results become readble
