我有一个 HTML 表格,我希望能够在单击按钮后添加一行,并弹出一个对话框,我可以在其中输入必要的行信息。我遇到了一些代码,它完全符合我的要求。我对其进行了尽可能地与我的代码相匹配的定制。到目前为止,我有弹出框,但在我单击弹出窗口中的“添加行”后,它没有添加行,而这正是我需要它做的。我希望有人能够告诉我这有什么问题。我对此很困惑。

JavaScript:

// ----- Dialog Box -----

$( function() {
var dialog, form,

emailRegex = /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/,
mr_name = $( "#mr_name" ),
buyer_id = $( "#buyer_id" ),
poc_n = $( "#poc_n" ),
poc_e = $( "#poc_e" ),
poc_p = $( "#poc_p" ),
allFields = $( [] ).add( mr_name ).add( buyer_id ).add( poc_n ).add( poc_e ).add( poc_p ),
tips = $( ".validateTips" );

function updateTips( t ) {
tips
.text( t )
.addClass( "ui-state-highlight" );
setTimeout(function() {
tips.removeClass( "ui-state-highlight", 1500 );
}, 500 );
}

function checkLength( o, n, min, max ) {
if ( o.val().length > max || o.val().length < min ) {
o.addClass( "ui-state-error" );
updateTips( "Length of " + n + " must be between " +
min + " and " + max + "." );
return false;
} else {
return true;
}
}

function checkRegexp( o, regexp, n ) {
if ( !( regexp.test( o.val() ) ) ) {
o.addClass( "ui-state-error" );
updateTips( n );
return false;
} else {
return true;
}
}

function addVendor() {
var valid = true;
allFields.removeClass( "ui-state-error" );

valid = valid && checkLength( mr_name, "mr_id", 3, 16 );
valid = valid && checkLength( buyer_id, "buyer_id", 6, 80 );
valid = valid && checkLength( poc_n, "poc_n", 5, 16 );
valid = valid && checkLength( poc_e, "buyer_id", 6, 80 );
valid = valid && checkLength( poc_p, "poc_n", 5, 16 );

valid = valid && checkRegexp( mr_id, /^[a-z]([0-9a-z_\s])+$/i, "Username may consist of a-z, 0-9, underscores, spaces and must begin with a letter." );
valid = valid && checkRegexp( buyer_id, /^([0-9a-zA-Z])+$/, "Password field only allow : a-z 0-9" );
valid = valid && checkRegexp( poc_n, /^([0-9a-zA-Z])+$/, "Password field only allow : a-z 0-9" );
valid = valid && checkRegexp( poc_e, emailRegex, "eg. ui@jquery.com" );
valid = valid && checkRegexp( poc_p, /^([0-9a-zA-Z])+$/, "Password field only allow : a-z 0-9" );

if ( valid ) {
$( "#html_master tbody" ).append( "<tr>" +
"<td>" + mr_name.val() + "</td>" +
"<td>" + buyer_id.val() + "</td>" +
"<td>" + poc_n.val() + "</td>" +
"<td>" + poc_e.val() + "</td>" +
"<td>" + poc_p.val() + "</td>" +
"</tr>" );
dialog.dialog( "close" );
}
return valid;
}

var dialog = $( "#dialog-form" ).dialog({
autoOpen: false,
height: 400,
width: 350,
modal: true,
buttons: {
"Add Row": addVendor,
Cancel: function() {
dialog.dialog( "close" );
}
},
close: function() {
form[ 0 ].reset();
allFields.removeClass( "ui-state-error" );
}
});

form = dialog.find( "form" ).on( "submit", function( event ) {
event.preventDefault();
addVendor();
});

$( "#create-user" ).button().on( "click", function() {
dialog.dialog( "open" );
});
} );

我知道验证现在已关闭,但这不是我当前的重点。我只是希望能够在填充弹出窗口后添加一行。

最佳答案

我把你的代码放在 this fiddle 中,去掉PHP部分,以便更好的调试。我不确定您是否知道一件事,尽管它非常有用,但您可以使用浏览器的控制台(右键单击 > 检查 > 控制台)来查找最终的 JS 错误。

无论如何,当您单击添加行时没有发生任何事情,因为您的脚本中存在一些错误。

1) 此行:mr_name = $( "#mr_name"), 应为 mr_name = $( "#mr_id"),,因为 mr_id 是您为 HTML 输入提供的 id

2) 这一行: valid = valid && checkRegexp( mr_id,/^[a-z]([0-9a-z_\s])+$/i, "用户名可以由 a-z, 0-9 组成、下划线、空格并且必须以字母开头。"); 应该有 mr_name 而不是 mr_id,因为它是您在我提到的行中命名的变量在上一项中
