Common JS output methods (5) and js output methods

I can work for you without much nonsense. The details are as follows:

1. alert ("content to be output ");

-> A dialog box is displayed in the browser, and the content to be output is displayed.

-> Alert converts the content to be output to a string and then

2. document. write ("content to be output ");

-> Directly display the output content on the page

3. console. log ("content to be output ");

-> Output content on the console

4. value-> assign values to the text box (Form element)

-> Get the content of the text box (Form element)

Document. getElementById ("search"). value = "content to be added to the # search text box ";

5. innerHTML/innerText-> assign values to tags except form elements

Document. getElementById ("div1"). innerHTML = "alright ";
Document. getElementById ("div1"). innerText = "alright ";

-> Differences Between innerHTML and innerText

1) When innerHTML is assigned a value, if a valid HTML Tag is processed as a real tag, the tag can play its own role;

InnerText whether or not labels are assigned values as text, all the values are text, and tags do not play their own role;

(When assigning values, innerHTML can recognize HTML tags, but innerText cannot)

2) innerText is not supported in some Firefox browsers, while innerHTML is supported by all browsers.
