我正在尝试为我的公司设置“点击聊天”系统。它需要一个从用户那里获取一些信息的表格。提交表单时，应该使用.js文件中的脚本打开一个新窗口。
我尝试添加一些验证，这导致了onclick和onsubmit功能。如果表单未经验证而被子化，它将使用BG.startChatWithIssueForm(this.form, true);函数打开一个新窗口。但是，出于某种原因，当我包含onsubmit进行验证时，onclick会完全忽略它。
我已尝试将BG.startChatWithIssueForm(this.form, true);函数嵌套在formValidator()函数的不同位置，但仍会导致文件下载提示而不是打开新窗口。
不确定我做错了什么。我已经研究了几个星期，似乎无法想出任何东西。 Javascript绝对不是我的强项，所以任何帮助都将不胜感激。
请参阅以下代码：
JS：
function Bomgar() {
var _host = "";
var _protoRe = /^(http|https):\/\//;
/* private */
function _createURL(params, forPopup) {
var qStr = "";
for (var k in params) {
qStr += "&"+encodeURIComponent(k)+"="+encodeURIComponent(params[k]);
}
qStr = "popup="+(forPopup ? "1" : "0") + "&c2cjs=1" + qStr;
return _host+"api/start_session.ns?"+qStr;
};
function _openWindow(params) {
return window.open(_createURL(params, true), 'clickToChat', 'toolbar=no,directories=no,status=no,menubar=no,resizable=yes,location=no,scrollbars=no');
};
function _redirectWindow(params) {
window.location.href = _createURL(params, false);
};
function _startChat(params, doFull) {
var w = _openWindow(params);
if (w && !w.closed) { return; }
else if (doFull) { _redirectWindow(params); return; }
};
function _startChatWithSurveyValues(surveyValues, fallbackToFullWindow) {
surveyValues.issue_menu = '1';
_startChat(surveyValues, fallbackToFullWindow);
};
/* public */
// Set the public site hostname that click to chat should be started on.
this.setSite = function(siteHostname) {
if (!_protoRe.test(siteHostname)) { siteHostname = "http://"+siteHostname; }
if (siteHostname[siteHostname.length-1] != '/') { siteHostname += '/'; }
_host = siteHostname;
};
// Start a click to chat session using a session key, optionally falling back to a full browser window redirect if the popup window fails to open due to popup blockers.
this.startChatWithSessionKey = function(sessionKey, fallbackToFullWindow) {
var p = {short_key: sessionKey};
_startChat(p, fallbackToFullWindow);
};
// Start a click to chat session using a session key and external key, optionally falling back to a full browser window redirect if the popup window fails to open due to popup blockers.
this.startChatWithSessionKeyAndExternalKey = function(sessionKey, externalKey, fallbackToFullWindow) {
var p = {short_key: sessionKey, external_key: externalKey};
_startChat(p, fallbackToFullWindow);
};
// Start a click to chat session using just an issue id and no other front end survey fields.
this.startChatWithIssueId = function(issueId, fallbackToFullWindow) {
_startChatWithSurveyValues({id: issueId}, fallbackToFullWindow);
};
// Start a click to chat session by passing the entire front end survey form element.
// This will submit all non-button input element values on the form.
// Any unexpected survey field names will be ignored.
this.startChatWithIssueForm = function(formElement, fallbackToFullWindow) {
var params = {};
for (var i = 0; i < formElement.elements.length; i++) {
var e = formElement.elements[i];
if (e.name && e.value && e.type && e.type != 'button' && e.type != 'submit') {
params[e.name] = e.value;
}
}
formElement = undefined;
params.issue_menu = '1';
_startChat(params, fallbackToFullWindow);
return false;
};
// Start a session with a representative id and name.
this.startChatWithRepIdName = function(repId, repName, fallbackToFullWindow) {
var p = {id: repId, name: repName};
_startChat(p, fallbackToFullWindow);
};
return this;
}

答案 0 :(得分：3)
您是否尝试使用常规按钮替换提交按钮，在onClick处理程序中执行验证，然后从onClick处理程序中提交表单？
编辑：例如取代
<input onkeypress="return handleEnter(this, event)" type="submit" value="Submit" onclick="BG.startChatWithIssueForm(this.form, true); return false;" />
与
<input onkeypress="return handleEnter(this, event)" type="button" value="Submit" onclick="BG.handleSubmit(this.form, true);" />
那么也许可以使用这样的Javascript函数（我不确定你希望这些事情发生在什么顺序）：
BG.handleSubmit = function(formElement, fallBackToFullWindow) {
if (!formValidator())
return;
BG.startChatWithIssueForm(formElement, fallBackToFullWindow);
formElement.submit();
return false;
}
编辑：如果发现某些内容无效，您的验证函数可能会返回false。
