我正在为我的项目使用Jquery Select2。我想在加载页面时在单个输入字段中保留默认值。我试图通过设置initSelection
而我开始这样的select2组件。select2单个字段的默认值
$(document).ready(function() {
allowClear: true,
ajax: { // instead of writing the function to execute the request we use Select2's convenient helper
dataType: 'json',
url: "public/data.php",
data: function (term, page) {
return {
q: term, // search term
component: "map",
all_selected: $("#map-all").hasClass("active"),
parent_value: $("#city").val(),
child_value: ""
};
},
results: function (data, page) { // parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to alter remote JSON data
return {results: data};
}
},
initSelection: function(element, callback) {
return $.getJSON("public/data.php?q="+element.val()+"&component=map&all_selected=false&parent_value=&child_value=", null, function(data) {
if ($.isFunction(callback)) {
return callback(data);
}
});
},
formatSelection: format,
formatResult: format,
});
但是,这不起作用,因为它应该是。
但是,当我将multiple: true,
设置为select2选项时,此功能完美无缺。我如何为单隐藏领域做到这一点?
谢谢&关心!
