有没有办法可以在HTML中的select2中设置所选的id / text,就像显示和选择一样?
我正在使用jquery select2版本4.0.0
这是代码:
$("#users").select2({
placeholder: "select user...",
escapeMarkup: function (markup) { return markup; },
ajax: {
url: "users.json",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term, // search term
page: params.page
};
},
processResults: function (response, page) {
return {
results: response.data
};
},
cache: true
},
templateResult: function(item){
if (item.loading) {
return item.text;
}
return item.username + " <small><i>(" + item.role + ")</i></small> "; // display data in html
},
templateSelection: function(item){
if (item.username){
return item.username + " <small><i>(" + item.role + ")</i></small> "; // select row in html
}
return item.text; // for placeholder
}
});
要设置所选值,我会这样做:
// bring data for to set selected value, data contains fields data
var selected_user_id = data.id,
// this is the content that I need to use as it is HTML content
selected_user_text_html = data.username + " <small><i>(" + data.role + ")</i></small> ",
// this is the one that I am using and is not html because there is no way to put html inside a option select item
selected_user_text_regular = data.username + " (" + data.role + ") ";
// set selected value
$("#users").append("<option value='"+selected_user_id+"' selected='selected'>"+selected_user_text_regular+"</option>");
// trigger update
$("#users").trigger("change");
有没有办法可以用HTML而不是纯文本设置所选文本?

是的,你可以。 Select2有两个有用的选项“ templateSelection ”和“ templateResult ”两个都是函数,你可以创建任何你想要的html包装器。 只需将选项传递给select2()方法,就像这样..
var data = [{id: 100, text: "AAAAAA"}, {id: 200, text: "BBBB"}]
var formatState = function(result) {return $("<b>"+result.text+"</b>")}
var formatSelection = function(selection){return $("<b>"+selection.text+"</b>") }
$(".js-example-basic-single").select2({ data:data,templateResult: formatState, templateSelection: formatSelection
}).val(100).change();
您应该会看到选项ID为100的选项。
我希望我能帮到你;

如果我理解正确的话,
根据api https://select2.github.io/examples.html ,您可以通过将其置于html标记中然后调用javascript
来设置所选内容the function cider-find-var is not known

假设在声明上调用ajax
当ajax返回时,你是否能够附加选项。
var data = [
{ id: 0, text: 'enhancement' },
{ id: 1, text: 'bug' },
{ id: 2, text: 'duplicate' },
{ id: 3, text: 'invalid' },
{ id: 4, text: 'wontfix' }
]
$(".example").select2({
data: data
})
<select class="example">
<option value="3" selected="selected">invalid</option>
</select>
同时更新
请考虑以下内容以替换您的其他代码或提供您的想法
ajax: {
...
processResults: function (response, page) {
//something like
$.each( response.data, function( i, obj ) {
if(obj.selected)
{
var elem = $('#users')
elem.append($('<option>', {
value: obj.value,
text : obj.text,
selected : "selected"
}));
}
})
return {
results: response.data
};
},
cache: true
},
