答案 0 :(得分：0)
创建一个额外的函数，将其用作动作<div id="nav-buttons">
</div>
<script>
var totalRecords = 500;
var recordsPerPage = 50;
var totalButtons = totalRecords/recordsPerPage;
var navButtons = document.getElementById("nav-buttons");
console.log(totalButtons)
for (var b=0; b<totalButtons;b++)
{
var button = document.createElement("button");
button.setAttribute("pageto", b);
button.innerHTML="Page " + b;
navButtons.appendChild(button);
button.addEventListener("click", function(event) {
var btn = event.target;
var page = btn.getAttribute("pageto");
navButtons.appendChild(btn);
alert(page);
// goto(page) -- write your function for getting the records for page[page]
});
}
</script>参数
selector然后添加
func helperFunc() {
self.saveItems(dataToSave)
}
