Question

javascript 代码生成一个span标签，但是当点击该标签时要调用某个函数，而且需要传参数，这参数该怎么传？

//添加行
function addRow(customer, cusAddr) {
var tblObj = document.getElementById("tblDiv");
var newRow = tblObj.insertRow(tblObj.rows.length - 2);
var newColCustomer = newRow.insertCell(newRow.cells.length);
var newSelect = newRow.insertCell(newRow.cells.length);
newColCustomer.innerHTML = customer;
newSelect.innerHTML = "<span style='cursor:hand;' onclick='showAddress(customer)'">[选择]</span>"
alert(newSelect.innerHTML);
}
function showAddress(customer) {
alert(customer);--结果是[object Object]
document.getElementById("customerName").value = customer;//结果object
//document.getElementById("address").value = cusAddr;
alert("----------------------------------");
}

Answer 1

<script>
function mover(obj)
{
obj.style.backgroundColor="#00ccff";
obj.style.borderWidth="2px";
obj.style.borderStyle="dashed";
}
function mout(obj)
{
obj.style.backgroundColor="White";
obj.style.borderWidth="1px";
obj.style.borderStyle="solid";
}
</script>
<span style="border-style:solid;border-width:1px;" onmouseover="mover(this)" onmouseout="mout(this)">This is a span</span>

Answer 2

newSelect.innerHTML = "<span style='cursor:hand;' onclick='showAddress(“+customer+”)'">
这句这样改一下

Answer 3

newSelect.innerHTML = "<span style='cursor:hand;' onclick='showAddress(\"" + customer+"\");'">[选择]</span>"

为什么要加\呢？能解释一下吗
我加了\后，就能成功了。

\表示转义，指示后面跟的那个是字符串里的字符
而不是与最前面的双引号配对用的
