我正在尝试调用由与按钮链接的onclick标记确定的javascript函数。但是，javascript方法调用似乎无法正常工作。 javascript是外部的，因此我没有使用任何内联脚本。
我也希望将按钮的值从一个 Electron 窗口存储到另一个 Electron 窗口，而不使用PHP将其存储在本地存储中。另一个html页面是“c_card_prepaid_bank.html”
这里的上下文允许用户选择要支付的金额。

Javascript Utilities.js
//Get Amount in Euros
document.getElementById("set10").onclick = getA();
function getA() {
localStorage.setItem('pre', "10");
}
const a = localStorage.getItem('pre');
document.getElementById("preAmount").innerHTML = "Credit Amount: " + a;
最佳答案
做类似的事情:
document.getElementById('set10').addEventListener("click", function() {
localStorage.setItem('pre', "10");
});
const a = localStorage.getItem('pre');
document.getElementById("preAmount").innerHTML = "Credit Amount: " + a;
