Do you want the return result in fun1() to be used as the execution js statement? ? You can use eval() to execute

You can directly define fun1 to return the text of the specifiedclassNameDOM, and then just run it directly. Anyway, when you generate code, you want to execute it immediately.

function func1(className) { return $(className).find("p").text(); } for (var i = 0; i < $(".name").length; i++) { console.log(`name${i} p:`, func1(`.name${i}`)); }

You don’t need to dynamically generate scripts, the script itself is very flexible. The code below is equivalent to the one you want to generate

var textArray = $(".name p") .map(function() { return $(this).text() }).toArray();

If you want to loop through each.name pyou can directly

$(".name p") .each(function() { $p = $(this); // .... })

If you want to process the specified name, you can

// ES6 语法，若需要可转换为 es5 的 var textArray = ["name1", "name2", "namen"] .map(name => $(`.${name}`)) .map($name => $name.children("p").text()); // 这里本来就是原生数组，不需要 toArray()

So what you want to do must be handled by dynamically generated scripts? If it is really needed, this is usually done by the server, not the front end. If the front-end can generate a script to run, it can definitely run a certain piece of code directly...
