[英]Yii2: Is there an easy way to load an existing ActiveForm with values from Javascript?
I have an existing Yii2 ActiveForm (like the one below) on a Single-Page-App where I want to load new values into it via AJAX. 我在Single-Page-App上有一个现有的Yii2 ActiveForm(如下图所示),我想通过AJAX将新值加载到其中。 Is there already a simple way to do that, or do I need to make my own Javascript function to do that? 是否已经有一种简单的方法可以执行此操作,或者我需要创建自己的Javascript函数来执行此操作?
<form>
<input type="text" name="Conversation[cv_timestamp]">
<input type="text" name="Conversation[cv_type]">
<input type="text" name="Contact[ct_firstname]">
<input type="text" name="Contact[ct_lastname]">
</form>
So, if I understand you correctly, you want your controllers to save your model data via ajax? 因此,如果我理解正确,您是否希望控制器通过Ajax保存模型数据?
If that's the case, you should take a look at ActiveControllers . 如果是这样,您应该看看ActiveControllers 。
Basically, you will have: 基本上,您将拥有:
exposed via different verbs to use them as an API. 通过不同的动词公开以将其用作API。
I ended up making my own Javascript function. 我最终制作了自己的Javascript函数。 Improvements are welcome. 欢迎改进。
// Load ActiveForm with new model attributes via Javascript
//
// Form fields must have been named like this: <input name="Contact[firstname]"> <input name="Contact[lastname]">
//
// @param {(string|jQuery object)} formSelector - String with selector or a jQuery object
// @param {object} models : Object where keys match the 1st level form field names and the values are the model attributes that match the 2nd level, eg.: {Contact: {firstname: 'John', lastname: 'Doe'}, }
function loadActiveForm(formSelector, models) {
if (!(formSelector instanceof jQuery)) {
formSelector = $(formSelector);
}
$.each(models, function(modelName, model) {
$.each(model, function(attributeName, attributeValue) {
$input = formSelector.find(':input[name="'+ modelName +'['+ attributeName +']"]');
if ($input.length > 1) {
if ($input.first().is(':radio')) {
$input.each(function() {
if ($(this).val() == attributeValue) {
$(this).prop('checked', true).click();
if ($(this).closest('.btn').length > 0) {
$(this).closest('.btn').button('toggle');
}
}
});
} else {
alert('In loadActiveForm an input had multiple tags but they are not radio buttons.');
}
} else {
$input.val(attributeValue);
}
})
});
}
