美好的一天!
我的表单有我的按钮的javascript函数,用于从表中添加行并重置表单中的文本字段。
在我的添加按钮中,我有一个递增变量rowCount
,用于计算行数。它运作良好,并按我的预期工作。当我把它放在<form></form>
标记内时,它会停留在2,不会增加,也不会添加任何行。
这是我的代码,供我们参考,也可以调试。提前谢谢!
var rowCount = 1;
function addRow() {
var table = document.getElementById('tblOrder');
rowCount = rowCount + 1;
var row = table.insertRow(rowCount);
var cell0 = row.insertCell(0);
var cell1 = row.insertCell(1);
var cell2 = row.insertCell(2);
var cell3 = row.insertCell(3);
var cell4 = row.insertCell(4);
var cell5 = row.insertCell(5);
cell0.innerHTML = "<input type='text'>";
cell1.innerHTML = "<input type='number'>";
cell2.innerHTML = "<input type='text'>";
cell3.innerHTML = "<input type='text'>";
cell4.innerHTML = "<input type='text'>";
cell5.innerHTML = "<input type='text'>";
alert(rowCount)
}
function resetForm() {
document.getElementById('orderForm').reset();
alert('All cleared!')
}

答案 0 :(得分:1)
如果按钮放在表单中,默认情况下它们将成为提交按钮,这意味着它们在单击时提交表单。如果表单没有指定操作,则会将其提交到与页面相同的URL,从而导致页面被刷新。这就是你的情况。
要阻止按钮提交表单,请将其type
设置为通用按钮而不是提交按钮:
<button type="button"></button>
