这个问题在我身边已经刺了一个月了。如果有人能搞清楚,我会非常非常非常感激。
这适用于Chrome,但不支持FF。
之前我认为这只是PUT的一个问题,但事实上即使是这个绑定中的console.log也没有触发。
您可以在此处查看之前的讨论:
Why does this jQuery AJAX PUT work in Chrome but not FF
这里有很多周围的HTML:
<div id="createTeamModal" class="small reveal-modal">
<form id="createTeamForm">
<div class="row"><p id="teamFlavorText" class="lead">Building a new team</p></div>
<div class="row">
<div class="small-4 large-4 columns"><label>Team Name:</label></div>
<div class="small-6 large-6 columns"><input name="teamName" id="teamName" type="text" size="20"/></div>
</div>
<div class="row"><p class="lead">Does this team work for a business?</p></div>
<div class="row">
<div class="small-4 large-4 columns"><label>Business Size:</label></div>
<div class="small-6 large-6 columns">
<select id="businessSizeSelect" name="businessSizeSelect">
<%
Info[] sizes = is.getList("business_sizes");
for (Info size : sizes) {
out.print("<option value=\"" + size.getId() + "\">" + size.getDescription() + "</option>");
}
%>
</select>
</div>
</div>
<div id="businessLocationDiv" class="row" style="display: none; margin-top: 20px;">
<div class="small-4 large-4 columns"><label>Business Location:</label></div>
<div class="small-6 large-6 columns">
<select id="businessLocationSelect" name="businessLocationSelect">
<%
Info[] locations = is.getList("business_locations");
for (Info location : locations) {
out.print("<option value=\"" + location.getId() + "\">" + location.getDescription() + "</option>");
}
%>
</select>
</div>
</div>
<div id="businessTypeDiv" class="row" style="display: none; margin-top: 20px;">
<div class="small-4 large-4 columns"><label>Industry:</label></div>
<div class="small-6 large-6 columns">
<select id="businessTypeSelect" name="businessTypeSelect">
<%
Info[] types = is.getList("business_types");
for (Info type : types) {
out.print("<option value=\"" + type.getId() + "\">" + type.getDescription() + "</option>");
}
%>
</select>
</div>
</div>
<div class="row" style="margin-top: 20px;">
<div class="large-offset-10 small-1 large-1 columns">
<button id="createTeamButton" class="small button">Create</button>
</div>
</div>
</form>
<a class="close-reveal-modal">×</a>
</div>
这是javascript。这嵌套在document.ready()。
中$("#createTeamButton").click(function () {
console.log("here");
window.alert("here");
var teamObject = new Team();
teamObject.description = $("#teamName").val();
teamObject.businessSize = $("#businessSizeSelect").val();
teamObject.businessType = $("#businessTypeSelect").val();
teamObject.businessLocation = $("#businessLocationSelect").val();
console.log("There");
$.ajax({
type: "PUT",
url: "/ajax/rest/team",
dataType: "json",
data: JSON.stringify(teamObject),
success: function () {
// Reload the team select box
loadTeamSelectBox();
// Pop up the site create modal
$('#createSiteModal').foundation('reveal', 'open');
},
error: ajaxErrorHandler
});
});
这是Team对象:
function Team() {
var id=0, description='', businessSize=0, businessType=0, businessLocation=0, invite="";
}
如果我填写团队字段然后在控制台中运行createTeamButton.click()事件,那么PUT请求将记录在控制台中,但它是红色的,我在Fiddler中看不到它。这些是请求标头:

Firefox正在阅读按钮按下作为表单提交,即使我从未绑定按钮点击.submit。解决方案很简单,只需要花费很长时间来解决问题。

Team对象在哪里?
您希望获取值的这些html属性在哪里? $( “#businessSizeSelect”)VAL();
理想情况下,这些对象需要嵌套在表单
中<form>
<input type="text" id="teamName">
</form>

尝试使用on()代替click()
$("#createTeamButton").on("click", function () {
///code
});
答案 3 :(得分:0)
可能有两个原因
您的代码未在ready
上执行
执行单击事件注册代码时,dom未正确加载
解决方案
将代码移至ready
$(function(){
$('#createTeamButton').click(function(){....})
})
使用load()
动态地将html加载到加载状态
解决方案
使用基于事件传播的事件处理程序
$(document).on('click', '#createTeamButton', function(){
....
})
答案 4 :(得分:0)
我在动态添加的按钮上遇到了类似的问题。有三个问题在起作用:
1)上面Jude Duran建议的第一个是从按钮变为输入
<input type='button' Value='Button' class='btnclass' myattribute='foobar' >
2)然后我使用了.bind函数而不是click事件
$('[id^=Compare]').bind("click", function (event) {
alert(event.attributes.myattribute,value);
// returns foobar
}
3)最后一个元素是我需要(如上所述)在eventhandler“function(event)”中显式声明事件对象。在Chrome中,对象事件似乎自动存在(即使使用“function()”存在一个我可以查询其属性的对象事件,而在FF中我必须明确声明它。
//Works in Chrome but not FF
$('[id^=Compare]').bind("click", function () {
alert(event.attributes.myattribute,value);
// returns foobar
}
希望这有助于其他人遇到这个神秘的问题。
