在按下按钮时显示电子邮件中的HTML下拉选择 [英] Displaying HTML Dropdown Selection in Email on Button Press
问题描述
我有一个表格,您可以通过选中某个复选框来选择某些行,然后在点击一个按钮时,会弹出一个电子邮件客户端并将这些选择粘贴到电子邮件正文中。这工作得很好。
我正在努力的是,我需要从下拉列表中粘贴选择内容,但无法将该功能集成到我的代码。我怎么能这样做?
HTML选择:
< select id =pos-droponChange =updateinput();>
<选项已禁用> POS - City< / option>
<?php foreach($ pos-> fetchAll()as $ city){?>
< option class =pos-cityvalue =<?php echo $ city ['POS'];?>><?php echo $ city ['POS'] ;? >< /选项>
<?php}?>
< / select>
JavaScript ... pos_city_selected变量包含当前的下拉列表选择:
var input_num;
var pos_city_selected;
var pos_city_selected1;
function updateinput(){
var pos_city = document.getElementById(pos-drop);
pos_city_selected = pos_city.options [pos_city.selectedIndex];
if(pos_city_selected){
pos_city_selected1 = true;
}
console.log(pos_city_selected);
console.log(pos_city_selected1);
$(function($){
var RowData =(function(storage,storageKey){
var rowData = readFromSession();
var dataItems = ['loc','rp-code','sku','special-id','description','quantity','unit'];
var emailDelimiters = {
'行':'%0D%0A',
'dataItem':'\xa0\xa0'
};
函数readFromSession(){
return JSON.parse storage.getItem(storageKey)||'{}');
}
函数writeToSession(){
storage.setItem(storageKey,JSON.stringify(rowData));
}
函数writeRow(tr){
var $ tr = $(tr),
id = $ tr.prop('id');
if($ tr.find ('.check')。is(':checked')){
rowData [id] = {};
for(var i = 0; i< dataItems.length; i ++){
rowData (id)[dataItems [i]] = $ tr.find('。'+ dataItems [i]).text();
}
input_num = rowData [id] .quantity_num = $ tr.find('。spinner')。val(); //如果使用HTML5< input type =number>
} else {
delete rowData [id];
}
writeToSession();
}
函数readRow(tr){
//从存储的数据中恢复tr的复选框和微调值
var $ tr = $(tr),
id = $ tr.prop('id'),
row = rowData [id];
if(row){
$ tr.find('。check')。prop('checked',true).end()
// .find('。spinner') .spinner('value',row.quantity_num); //如果使用微调控件
.find('。spinner')。val(row.quantity_num); //如果使用HTML5< input type =number>
$ b函数toEmailString(){
return $ .map(rowData,function(row,id){
return $ .map(row,window。 encodeURIComponent).join(emailDelimiters.dataItem);
});
//选择性地将函数暴露为RowData的方法
return {
'writeRow':writeRow,
'readRow':readRow,
'toEmailString ':toEmailString
};
})(window.sessionStorage,'checkedRowData'); $($#
$('#merchTable')。on('change','.check',function(){//关于更改表格行...
RowData.writeRow($ (this).closest('tr')。get(0)); // ...在RowData和sessionStorage中设置相应的行对象
})。on('change','.spinner',function (){//离开一个微调元件
RowData.writeRow($(this).closest('tr')。get(0));
}); $('#checkout')。on('click',function(){//点击[Checkout]按钮
console.log(input_num);
如果(input_num> quantity_num){
alert(输入的数字不能大于数量。);
} else if(pos_city_selected1!= true){
alert(Please );
}其他{
var link =mailto:me@example.com+?subject =+ encodeURIComponent( Order)+& body =+ RowData.toEmailString();
console.log(link);
window.location.href = link;
}
} );
//完成每个分页/搜索时调用此函数
函数restoreVisibleRows(){
$('#merchTable tbody tr')。get()。forEach(RowData .readRow);
}
restoreVisibleRows();
});
建议的方法:
- 删除这三个变量,
input_num
等和函数updateinput(){...
- 添加一个public
RowData.validityCheck()
方法,它如果在rowData中遇到错误,则抛出它,例如,输入的量大于其相应的量 - 可用。
- 使用
try {} catch {}
$ b $结构的结构('click',function(){//点击[Checkout]按钮
尝试{
/ $('#$ checkout')。 /(1)对所选行进行有效性检查
RowData.validityCheck(); //如果检测到错误,则会抛出
//(2)对#pos_drop选项执行有效性检查
var pos_city = $( #POS降)VAL()。
if(!pos_city){
throw new Error('请从下拉列表中选择一个POS城市。');
(3)在这里执行任何进一步的有效性检查(并相应地抛出)
//如果没有遇到有效性错误,执行只会到达这一点。
var link =mailto:me@example.com+?subject =+ encodeURIComponent(Order)+& body = Location:+ pos_city +'%0D%0A'+ RowData。 toEmailString(); //检查分隔符。
console.log(link);
window.location.href = link;
}
catch(e){
console.error(e);
$('#userMessage')。text(e.message); // element #userMessage - 例如一个< span> - 需要在页面某处存在
}
});
I have a table where you can select certain rows by checking a checkbox and, on a button click, it will bring up an email client and paste those selections into the email body. This works just fine.
What I am struggling with is that I need to get it to also paste in the selection from the dropdown list but am having trouble integrating that functionality into my code. How could I do this?
HTML select:
<select id="pos-drop" onChange="updateinput();">
<option selected disabled>POS - City</option>
<?php foreach($pos->fetchAll() as $city) { ?>
<option class="pos-city" value="<?php echo $city['POS'];?>"><?php echo $city['POS'];?></option>
<?php } ?>
</select>
JavaScript...the pos_city_selected variable holds the current dropdown list selection:
var input_num;
var pos_city_selected;
var pos_city_selected1;
function updateinput() {
var pos_city = document.getElementById("pos-drop");
pos_city_selected = pos_city.options[pos_city.selectedIndex];
if (pos_city_selected) {
pos_city_selected1 = true;
}
console.log(pos_city_selected);
console.log(pos_city_selected1);
}
$(function($) {
var RowData = (function(storage, storageKey) {
var rowData = readFromSession();
var dataItems = ['loc', 'rp-code', 'sku', 'special-id', 'description', 'quantity', 'unit'];
var emailDelimiters = {
'row': '%0D%0A',
'dataItem': '\xa0\xa0'
};
function readFromSession() {
return JSON.parse(storage.getItem(storageKey) || '{}');
}
function writeToSession() {
storage.setItem(storageKey, JSON.stringify(rowData));
}
function writeRow(tr) {
var $tr = $(tr),
id = $tr.prop('id');
if($tr.find('.check').is(':checked')) {
rowData[id] = {};
for(var i=0; i<dataItems.length; i++) {
rowData[id][dataItems[i]] = $tr.find('.' + dataItems[i]).text();
}
input_num = rowData[id].quantity_num = $tr.find('.spinner').val(); // if using HTML5 <input type="number">
} else {
delete rowData[id];
}
writeToSession();
}
function readRow(tr) {
// restore tr's checkbox and spinner value from stored data
var $tr = $(tr),
id = $tr.prop('id'),
row = rowData[id];
if(row) {
$tr.find('.check').prop('checked', true).end()
// .find('.spinner').spinner('value', row.quantity_num); // if using spinner widget
.find('.spinner').val(row.quantity_num); // if using HTML5 <input type="number">
}
}
function toEmailString() {
return $.map(rowData, function(row, id) {
return $.map(row, window.encodeURIComponent).join(emailDelimiters.dataItem);
});
}
// selectively expose functions as methods of RowData
return {
'writeRow': writeRow,
'readRow': readRow,
'toEmailString': toEmailString
};
})(window.sessionStorage, 'checkedRowData');
$('#merchTable').on('change', '.check', function() { // on changing a table row ...
RowData.writeRow($(this).closest('tr').get(0)); // ... set the corresponding row object in RowData and sessionStorage
}).on('change', '.spinner', function() { // on leaving a spinner widget
RowData.writeRow($(this).closest('tr').get(0));
});
$('#checkout').on('click', function() { // on clicking the [Checkout] button
console.log(input_num);
if (input_num > quantity_num) {
alert("The entered number cannot be greater than the quantity.");
} else if (pos_city_selected1 != true) {
alert("Please select a POS-City from the dropdown list.");
} else {
var link = "mailto:me@example.com" + "?subject=" + encodeURIComponent("Order") + "&body=" + RowData.toEmailString();
console.log(link);
window.location.href = link;
}
});
// Call this function on completion of every pagination/search
function restoreVisibleRows() {
$('#merchTable tbody tr').get().forEach(RowData.readRow);
}
restoreVisibleRows();
});
Suggested approach :
- delete those three vars,
input_num
etc and thefunction updateinput() {...}
, and any mention of them. - add a public
RowData.validityCheck()
method, which throws if it encounters an error in the rowData, eg an entered quanity is greater than its corresponding quantity-available. - employ a
try{} catch{}
structure in #checkout's click handler to orchestrate validity checking and act accordingly, as follows :
$('#checkout').on('click', function() { // on clicking the [Checkout] button
try {
// (1) perform validity check on the selected rows
RowData.validityCheck(); // will throw if error is detected
// (2) perform validity check on the #pos_drop selection
var pos_city = $("#pos-drop").val();
if (!pos_city) {
throw new Error('Please select a POS-City from the dropdown list.');
}
// (3) perform any further validity checks here (and throw accordingly)
// Execution will only reach this point if no validity error is encountered.
var link = "mailto:me@example.com" + "?subject=" + encodeURIComponent("Order") + "&body=Location: " + pos_city + '%0D%0A' + RowData.toEmailString(); // check that delimiter.
console.log(link);
window.location.href = link;
}
catch(e) {
console.error(e);
$('#userMessage').text(e.message); // element #userMessage - eg a <span> - needs to exist somewhere on the page
}
});
