这些答案我都不清楚。我终于找到了一个很好的解释

简单的答案是:
var search_term = new RegExp(search_term, "g");
text = text.replace(search_term, replace_term);
例如:
$("button").click(function() {
Find_and_replace("Lorem", "Chocolate");
Find_and_replace("ipsum", "ice-cream");
});
function Find_and_replace(search_term, replace_term) {
text = $("textbox").html();
var search_term = new RegExp(search_term, "g");
text = text.replace(search_term, replace_term);
$("textbox").html(text);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textbox>
Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum
</textbox>
<button>Click me</button>
