Today, I accidentally noticed that the password input boxes of QQ and HI cannot be deleted once with the mouse selected. I can only delete them one by one. Then I want to know how to achieve this effect in Js.
There are still a lot of Internet users, but I have tested a lot and found that it is not perfect. the browser is still playing a strange role. One method seems to only satisfy one browser.
Onselectstart = "Return false;", can meet the effect of IE. When it is only for a region, the statement of this segment is placed in a region. For example, <Div onselectstart = "Return false;"> ********* </div>, set onselectstart = "Return false;" directly in the body or use: document. onselectstart = function () {return false ;}
Style = "-moz-user-select: none;", can meet the effect in Firefox, because onselectstart = "Return false;" cannot produce the expected effect in Firefox, it can only be implemented in CSS mode. Of course, as before, when the entire document needs to achieve this effect, set the body style to-moz-user-select: none ;.
Finally, I have to talk about Google's Chrome browser. When the two methods are used in input, they cannot achieve the effect that the mouse cannot choose. So far, I have not found a good solution.
This is a test code compatible with most browsers:
<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<HTML xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312"/>
<Title> test </title>
</Head>
<Body>
<Div onselectstart = "Return false;" style = "-moz-user-select: none;"> you cannot select me </div>
</Body>
</Html>
