HTML strings are '< Div id = "a" > Aklsdjfklsjdfl< / div> 'such a string with an HTML special symbol, we usually have to process it before we output it so that it doesn't turn out to be a real HTML element. Become & amp; Lt; Such HTML symbol code.

If strings are long and have a lot of special symbols in them, how can we simply and efficiently transcode them all? Cycle? Regular expressions? Don't have to! And look:

function bian(a){return new Option(a).innerHTML}

That's all!

function bian(a){return new Option(a).innerHTML}

var a = '<div id="a">aklsdjfklsjdfl</div>';

alert(bian(a));
