jsfiddle hereの下部に、次のHTML があります。
<input type="text" id="BLAboxPaymentAmount" value="2">
</br>
<input type="text" id="BLAboxSection5Total" value="3">
..そしてこのjQuery：
$(document).on("focusout", '[id$=boxSection5Total]', function (e) {
var totalvalue = $(this).val();
//alert("boxSection5Total val is " + totalvalue);
var paymenttotalvalue = $('[id$=boxPaymentAmount]').val();
//alert("Payment Total val is " + paymenttotalvalue);
if (totalvalue !== paymenttotalvalue) {
alert("The value in 'Total' does not equal the previous value in 'Payment Total'");
} else {
alert("values ARE equal");
}
});
jsfiddle では問題なく動作しますが、Sharepoint ページでイベントが発生しません。 、私がすべきように、このjQueryに基づいています。これは、jsfiddleにあるものと実質的に同じです:
$(document).on("focusout", '[id$=boxSection5Total]', function (e) {
alert("focusout event has fired");
var totalvalue = $(this).val();
var paymenttotalvalue = $('[id$=boxPaymentAmount]').val();
if (totalvalue !== paymenttotalvalue) {
alert("The value in 'Total' does not equal the previous value in 'Payment Total'");
}
});
そのため、イベントは発生していません - なぜでしょうか?
Chrome と F12d でページを実行し、コンソールでエラー メッセージを探しましたが、何も見つかりませんでした。
アップデート
A. (「The」ではない) Wolff の場合:
これは、コード ビハインドで要素を作成する方法です。
boxPaymentAmount = new TextBox
{
CssClass = "dplatypus-webform-field-input"
};
また、jsfiddle の HTML で「textarea」を「text」に変更しました。

ジョナセン (ラッセルではない) クロウの場合:
jQuery を次のように変更しました。
$(document).on("blur", "[id$=boxSection5Total]", function (e) {
alert("blur event has fired");
console.log("blur event has fired");
var totalvalue = $(this).val();
var paymenttotalvalue = $('[id$=boxPaymentAmount]').val();
if (totalvalue !== paymenttotalvalue) {
alert("The value in 'Total' does not equal the previous value in 'Payment Total'");
console.log("The value in 'Total' does NOT equal the previous value in 'Payment Total'");
}
else {
console.log("The value in 'Total' DOES equal the previous value in 'Payment Total'");
}
});
...そして、このイベント ハンドラーからのコンソールにはまだ何も表示されません。

私はうまく起動する他の多くの関数/ハンドラーを持っています。なぜこれがそうでないのかは難問です。たぶん、私が持っているものを示すと（いくつかの悲惨な詳細を省略します）、何が起こっているのかを明らかにするかもしれません（失敗した機能は最後/一番下にあります）：
$(document).ready(function () {
console.log('The ready function has been reached; Requester and Payee Status sections should be slid up'); /* This is a "sanity check" so it can be verified that this jQuery script is running/ran */
});
/* NOTE: Things that need to take place after all the elements have been constructed need to go here; the ready function can be too early */
$(window).load(function () {
$('[id$=_AddressRows]').slideUp();
$('[id$=panelSection2]').slideUp();
$('[id$=panelSection3]').slideUp();
$('[id$=ddlPayToVendor]').hide();
});
/* NOTE: this checkbox is only visible if they are not already authenticated; If they select "Yes" (self-identify as UCSC Faculty, Staff, or Student), prompt them to log in */
$(document).on("change", '[id$=ckbxUCSCFacultyStaffOrStudent]', function () {
var ckd = this.checked;
. . . code elided for brevity
});
/* If user selects "payment for self" (they are seeking payment for themselves, as opposed to someone else), omit (invisibilize) sections 2 and 3 on the form TODO: Should I change these from "change" to "click" */
$(document).on("click", '[id$=rbPaymentForSelf]', function () {
if (this.checked) {
. . . code elided for brevity
}
});
/* If user selects "payment for someone else" (they are seeking payment for someone else, as opposed to themselves), make sections 2 and 3 on the form visible */
$(document).on("click", '[id$=rbPaymentForSomeoneElse]', function () {
if (this.checked) {
. . . code elided for brevity
}
});
$(document).on("click", '[id$=rbPaymentToIndividual]', function () {
if (this.checked) {
$('[id$=ddlPayToVendor]').slideUp();
$('[id$=ddlPayToIndividual]').slideDown();
}
});
$(document).on("click", '[id$=rbPaymentToVendor]', function () {
if (this.checked) {
$('[id$=ddlPayToIndividual]').slideUp();
$('[id$=ddlPayToVendor]').slideDown();
}
});
// Refactor this to populate the elements below (description, account codes, tax 1099); may pull from Lists rather than use the hardcoded vals, but if need to do the latter, see http://jsfiddle.net/clayshannon/x8npcpss/3/
$(document).on("change", '[id$=ddlPayToIndividual]', function () {
var value = $(this).val();
. . . code elided for brevity
});
// Refactor this ... (see comment above)
$(document).on("change", '[id$=ddlPayToVendor]', function () {
var value = $(this).val();
. . . code elided for brevity
});
/* Disallow anything other than 0..9 in the "SSN or ITIN" textbox */
$(document).on("keypress", '[id$=txtbxSSNOrITIN]', function (e) {
var k = e.which;
if (k < 48 || k > 57) { e.preventDefault(); }
});
$(document).on("click", '[id$=btnAddFoapalRow]', function (e) {
var textboxHeight = 15;
. . . code elided for brevity
});
$(document).on("keyup", "[id$=explainPaymentTextBox]", function (e) {
console.log("explainPaymentTextBox keyup reached");
while ($(this).outerHeight() < this.scrollHeight + parseFloat($(this).css("borderTopWidth")) + parseFloat($(this).css("borderBottomWidth"))) {
$(this).height($(this).height() + 1);
};
});
HERE IS THE RECALCITRANT ONE (DOESN'T FIRE):
/* Verify that amount in "Total" equals amount in Section 1 "Payment Amount"; this is not working at present; I first tried "focusout" instead of "blur" but neither event fires... */
$(document).on("blur", "[id$=boxSection5Total]", function (e) {
alert("boxSection5Total's blur event has fired");
console.log("boxSection5Total's blur event has fired");
var totalvalue = $(this).val();
var paymenttotalvalue = $('[id$=boxPaymentAmount]').val();
if (totalvalue !== paymenttotalvalue) {
alert("The value in 'Total' does not equal the previous value in 'Payment Total'");
console.log("The value in 'Total' does NOT equal the previous value in 'Payment Total'");
}
else {
console.log("The value in 'Total' DOES equal the previous value in 'Payment Total'");
}
});
