流星RangeError:超出最大调用堆栈大小.在按键事件上 [英] Meteor RangeError: Maximum call stack size exceeded. on keypress event
问题描述
我正在尝试创建一个搜索框，以过滤掉我在客户端中返回的收藏集的结果.
Im trying to make a search box to filter down results of my returned collection in the client.
但是，当我实际尝试搜索时，我在控制台中遇到了以上错误.
however when i actually try searching I'm getting the above error in the console.
RangeError: Maximum call stack size exceeded.
这是我的代码.
<body>
{{#isolate}}
<header class="row-fluid">
{{> modules}}
</header>
{{/isolate}}
<div id="main" class="span11">
{{#if currentUser}}
{{#isolate}}
{{> customers_list}}
{{/isolate}}
{{#isolate}}
{{> contacts_list}}
{{/isolate}}
{{/if}}
</div>
</body>
我在模块模板内的搜索表单
my search form in inside the modules template
<template name="modules">
{{templateLogger "modules"}}
<ul id="module_list" class="nav">
{{#each list}}
<li>
<a href="#" id="module_{{_id}}" module_id="{{_id}}" class="module">{{name}}</a>
</li>
{{/each}}
<form><input type="text" id="search"></form>
</ul>
和我要过滤结果的"customers_list"模板
and my customers_list template that I'm trying to filter the results
<template name="customers_list">
<table class="table">
<tr>
<th>Name</th>
<th>Address</th>
<th>City</th>
<th>State</th>
<th>Zip</th>
<th>Phone</th>
</tr>
{{#each record}}
<tr>
<td>{{name}}</td>
<td>{{address}}</td>
<td>{{city}}</td>
<td>{{state}}</td>
<td>{{zip}}</td>
<td>{{phone}}</td>
</tr>
{{/each}}
</table>
</template>
这是搜索表单的事件处理程序
and here is the event handler for the search form
Template.modules.events({
'keypress input#search': function (event) {
Session.set("currentFilter", $('input#search'));
}
});
和表单助手会显示结果
Template.customers_list.record = function() {
qry = Session.get("currentFilter") || "";
if (qry != "") {
return Customers.find({$or: [ {'name': qry}, {'address': qry}, {'city': qry}, {'state': qry} ] });
} else {
return Customers.find({competitor: null}, {sort: {name: 1}});
};
}
我不知道是什么原因导致了我从其他SO帖子上读到的关于该错误的错误，这似乎是一个无限循环，但是这些不是流星特有的问题，我不知道那是否会做出改变?还有一个无限循环，我也找不到.
I have no clue what the is causing this error from what i was able to read on other SO posts about the error it seems like its a infinite loop however those were not meteor specific questions and i don't know if that would make a difference? also if there is an infinite loop i cant find it.
任何帮助将不胜感激.
推荐答案
更改此内容
Template.modules.events({
'keypress input#search': function (event) {
Session.set("currentFilter", $('input#search'));
}
});
为此:
Template.modules.events({
'keyup input#search': function (event) {
Session.set("currentFilter", $('input#search').val());
}
});
我相信您只需要在输入字段的jQuery dom引用上使用.val().另外，我建议对事件使用keyup进行类似的操作.
I believe you just need the .val() on the jquery dom reference of the input field. Additionally I would recommend using keyup for the event for something like this.
为了获得想要的结果，您可能需要使用正则表达式.这就是我在应用程序中使用的内容.
For getting the results out like you want you likely want to use a regular expression. Here's what I'm using in my app.
Template.hudlies.found = function() {
var searchVal = Session.get("searchFilter");
if (searchVal != "") {
var searchResults = Hudlies.find({ name: { $regex: '^.*' + searchVal + '.*', $options: 'i' } });
};
return searchResults;
};
