我有一个正在尝试更新的运输模块。我希望能够为我的 php 表单/表格中的每个行项目添加行。最终发生的是根据需要为每个行项目显示添加/删除行按钮,但仅影响第一个行项目。如果我在行项目 1 中添加一行,它会正确添加一行。但是,如果我为订单项 2 添加一行,它实际上也为订单项 1 添加了一行。如果我尝试为行项目 3 添加一行,它会再次为项目 1 添加一行。我希望能够为每个项目添加行。
我在 php 中有一个调用 javascript 函数的 while 循环。问题是 javascript 中的变量之一需要一个 ID。尽管经历了我的循环,但 ID 永远不会改变,因此我的 javascript 仅适用于不是我想要的输出的单个循环。我在想如果我可以让 javascript 从 PHP 接收一个包含我的 ID 的变量,我可以让 javascript 在每次通过我的循环时运行。
这是我的javascript:
<SCRIPT language="javascript">
// Last updated 2006-02-21
function addRowToTable()
{
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow + 1;
var row = tbl.insertRow(lastRow);
// Item cell
var cellLeft = row.insertCell(0);
var textNode = document.createTextNode(iteration);
cellLeft.appendChild(textNode);
// Cust PN cell
var cellBox_Num = row.insertCell(1);
var el = document.createElement('input');
el.type = 'text';
el.name = 'Box_Num[]';
el.id = 'Box_Num' + iteration;
el.size = 18;
el.onkeypress = keyPressTest;
cellBox_Num.appendChild(el);
}
function keyPressTest(e, obj)
{
var validateChkb = document.getElementById('chkValidateOnKeyPress');
if (validateChkb.checked) {
var displayObj = document.getElementById('spanOutput');
var key;
if(window.event) {
key = window.event.keyCode;
}
else if(e.which) {
key = e.which;
}
var objId;
if (obj != null) {
objId = obj.id;
} else {
objId = this.id;
}
displayObj.innerHTML = objId + ' : ' + String.fromCharCode(key);
}
}
function removeRowFromTable()
{
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
if (lastRow > 1) tbl.deleteRow(lastRow - 1);
}
</SCRIPT>
这是我的循环:
