Recently in the learning time to see someone asked "find" and "find" the difference, found a lot of people say no difference, purely personal hobbies!
So I was curious to experiment, found a different result, through comparative analysis found "and" "(single quotes, double quotes), or there is a great difference!
Recommendation:<!--************ to prevent quotes from matching errors; single and double quotation marks cross-use *******************-->
When using the HTML onclick event attribute, it is wrong to use single quotation marks/double quotes, such as:
<!--************ to prevent quotes from matching errors; it is best to cross-use single and double quotes *******************--><InputType="Button"Value="Save"onclick="Savelocalstorage ("Form1 ")"/>
<!--Double quote Matching**********Error-
<Inputtype= "button "value=" Save "onclick=" Span style= "font-style:italic;" >savelocalstorage ( ' Form1 ') "/>
single and double quotes mixed *********** correct -->
Here is the test case source code:
