我的Google Chart,Twig和Symfony存在问题。我对一个函数进行ajax调用,该函数将数据发送到js函数绘图图表。我在图表之外显示数据并且运行良好。我还尝试在其中显示硬编码数据的图表,它也能很好地显示。只有当我将控制器中的数据放入图表的数据表中时,它才会起作用。
我没有显示我的控制器,因为它正确地发送数据。
这是我的代码:
绘图功能:
function drawGraphRepNoteOfColle() {
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Notes', 'Nombre'],
{% for r in repartitionsColle %}
[{{ r.note }}, {{ r.nombre }}],
{% endfor %}
]);
var options = {
chart: {
title: 'Company Performance',
subtitle: 'Sales, Expenses, and Profit: 2014-2017'
}
};
var chart = new google.charts.Bar(document.getElementById('graphRepNoteColle'));
chart.draw(data, options);
}
}
Ajax Call:
function rechargerColleStats() {
var groupes = document.getElementsByClassName("filled-in");
var groupesSelected = getSelectedGroupesOf(groupes);
var colleId = document.getElementById('collapside_colle_form_colles').value;
var numAdherent = document.getElementById('numAdherent').value;
var DATA = {groupesSelected: groupesSelected, idColle: colleId, numAdherent: numAdherent};
var request = $.ajax({
type: "POST",
url: "{{ path('paces_statistique_calculstatistique_getstatscolle') }}",
datatype: "html",
data: DATA,
success: function (response) {
document.getElementById("bodyColapColle").innerHTML = response;
drawGraphRepNoteOfColle();
document.getElementById("tableauQ").reload(true);
}
});
}
index.html.twig:
<nav class="top-nav panel-title">Statistiques</nav>
<div class="card-panel hoverable">
// Groupes selected field (checkboxes)
<div id="bodyColapGroupes">
{% include 'PACESStatistiqueBundle:Default:groupesCheckBoxes.html.twig' %}
</div>
// Form to get colleId
<fieldset style='display: inline; border: 2px solid deepskyblue;'>
<legend> Choix de la colle</legend>
{{ form_start(formColle) }}
{{ form_end(formColle) }}
</fieldset>
</div>
<div class="card-panel hoverable">
Colles
<div id="bodyColapColle">
{% include 'PACESStatistiqueBundle:Default:collapsideColle.html.twig' %}
</div>
</div>
collapsibleColle.html.twig:
<div id="colles">
<fieldset style='display: inline; border: 2px solid deepskyblue;'>
<legend> Minor </legend>
{% if minor is defined %}
{{ minor }} / {% if typeColle == 'QC' %}{{ nbQc }}{% else %}20{% endif %}
{% endif %}
</fieldset>
<div class="center">
<fieldset id="fieldchartA" style='height:100%; width: 100% ;border: 2px solid deepskyblue;'>
<legend> Chart1</legend>
<div id="graphRepNoteColle"></div>
</fieldset>
</div>
</div>
控制器中的getStatsColleAction:
$repartitionsColles=$em->getRepository( RepartitionColle::class )->findBy(['idStatColle'=>$statsColle]);
//on en recupere les données minor, major, medianne
$notes=array();
$nbRepartition = 0;
foreach($repartitionsColles as $repartitionsColle){
$repartition[$nbRepartition]['note'] = $repartitionsColle->getNote();
$repartition[$nbRepartition]['nombre'] = $repartitionsColle->getNombre();
$nbRepartition++;
}
array_multisort(array_column($repartition, 'note'), SORT_ASC, SORT_NUMERIC, $repartition);
发送的数组是$ repartition。 getNote()是一个浮点数,getNombre是一个整数。
绘图函数和Ajax调用在index.html.twig中。
GetStatsColle(使用AJAX调用的函数)返回带有所需数据的collapsideColle.html.twig。
Ajax工作正常:我发送其他信息并进行相同的调用,然后呈现。
答案 0 :(得分:0)
我建议不要依赖google.chart.load
每次绘制图表,
特别是如果你打算绘制多个图表,它应该每页只调用一次
相反,交换事物的顺序,首先从callback
开始,
然后你可以直接从ajax调用中绘制图表
您也可以在load
声明中包含google.charts.load('current', {
callback: rechargerColleStats,
packages:['bar']
});
function drawGraphRepNoteOfColle() {
var data = google.visualization.arrayToDataTable([
['Notes', 'Nombre'],
{% for r in repartitionsColle %}
[{{ r.note }}, {{ r.nombre }}],
{% endfor %}
]);
var options = {
chart: {
title: 'Company Performance',
subtitle: 'Sales, Expenses, and Profit: 2014-2017'
}
};
var chart = new google.charts.Bar(document.getElementById('graphRepNoteColle'));
chart.draw(data, options);
}
function rechargerColleStats() {
var groupes = document.getElementsByClassName("filled-in");
var groupesSelected = getSelectedGroupesOf(groupes);
var colleId = document.getElementById('collapside_colle_form_colles').value;
var numAdherent = document.getElementById('numAdherent').value;
var DATA = {groupesSelected: groupesSelected, idColle: colleId, numAdherent: numAdherent};
var request = $.ajax({
type: "POST",
url: "{{ path('paces_statistique_calculstatistique_getstatscolle') }}",
datatype: "html",
data: DATA,
success: function (response) {
document.getElementById("bodyColapColle").innerHTML = response;
drawGraphRepNoteOfColle();
document.getElementById("tableauQ").reload(true);
}
});
}
