我正在使用select2作为预先输入的东西:随着用户的输入,结果将根据更改的输入进行填充。我使用templateResult通过图像,按钮等来自定义搜索结果。templateSelection将仅将ajax JSON的某些部分返回到select2输入。
效果很好。
我现在正在使用数据表编辑器来显示表单。作为编辑器的一部分,当表单以编辑方式打开时,基于下面我的代码的相同URL ajax请求将向URL添加initialValue = true和value =“ something”参数。
在AJAX php页面上,我捕获是否initialValue = true,然后使用与发送的值相对应的JSON数据进行响应。
这是我的select2:
{
"label": "Attach to Contact:",
"name": "assigned_to_contact_id",
"type": "select2",
"opts": {
value: "",
initialValue: true,
ajax: {
url: "ajax_get_json.php?what=company_autocomplete_contacts",
dataType: 'json',
delay: 250,
data: function (params) {
return {
query: params.term, // search term
page: params.page
};
},
processResults: function (data, params) {
// parse the results into the format expected by Select2
// since we are using custom formatting functions we do not need to
// alter the remote JSON data, except to indicate that infinite
// scrolling can be used
params.page = params.page || 1;
return {
results: data,
pagination: {
more: (params.page * 30) < data.total_count
}
};
},
cache: true
},
escapeMarkup: function (markup) {
return markup;
}, // let our custom formatter work
minimumInputLength: 1,
templateResult: formatResults_editor,
templateSelection: formatResultsSelection_editor,
allowClear: true,
placeholder: {
"id": "",
"text": "(Searching all locations)"
}
}
}
以下是我的格式化功能:
function formatResults_editor(results) {
if (results.loading) {
return "Searching...";
}
//set image to contact pic
var image = '';
if (results.no_contact_pic_requested == 'Y') {
image = 'company_specific_files/contacts_images/no_pic_requested.png';
} else {
image = 'company_specific_files/contacts_images/' + results.company_id + '/' + results.id + '/' + 'webcam.jpg';
//check to see if the pic exists, else set default image
$.ajax({
type: "POST",
async: false,
url: 'company_specific_files/contacts_images/' + results.company_id + '/' + results.id + '/' + 'webcam.jpg',
error: function (response, status, xhr) {
//if no image present, use default image
image = 'company_specific_files/contacts_images/blank_avatar.png';
},
success: function (response, status, xhr) {
//this is how I see if there's an image: check the content-type response from ajax call. Make sure ajax is not async to work
var ct = xhr.getResponseHeader("content-type") || "";
if (ct == "image/jpeg") {
image = 'company_specific_files/contacts_images/' + results.company_id + '/' + results.id + '/' + 'webcam.jpg';
} else {
image = 'company_specific_files/contacts_images/blank_avatar.png';
}
}
});
}
var markup = "<div class='clearfix'><img style='float:left; padding-right: 5px' class='img-responsive' height='50' width='50' src='" + image + "'>" + ' ' + results.label + "</div>";
return markup;
}
function formatResultsSelection_editor(results) {
if (results.id === '') {
return '(Searching all locations)'; //placeholder added this way since using ajax per docs.
}
return results.contact_name + ' ' + results.birthdate;
}
当用户在select2中键入/搜索名称时,一切正常:填充该值,结果在下拉框中设置格式,结果在select2输入中显示为选择后。
现在,如果打开编辑器并填充select2的值,则AJAX请求如下所示:
ajax_get_json.php?what=company_autocomplete_contacts&initialValue=true&value=%224258%22
...,该页面的响应如下:
{"id":"1","text":"sample text","location":"Bayview","contact_name":"Mark","birthdate":"2010-05-28","label":"Mark from Bayview","value":"22","location_id":"4322","company_id":"432342","no_contact_pic_requested":"N"}
那么为什么select2不能像从templateSelection中选择的那样自动填充JSON响应标签?
在具有初始值的占位符时,在表单以编辑方式打开时,它仍会显示“正在搜索...”,实际上它应该像用户搜索时一样显示“标记(2010-05-28)”并选择templateResult选项。
据我所知,似乎没有任何进展。
答案 0 :(得分:0)
如果有人遇到过此事:
这与Datatables Editor有关。
我不能使用templateSelection。我用id和文本格式化结果。从那里开始,它将相应地填充。
