无法在 Laravel 5.4 中实时自动生成蛞蝓



我想在用户输入标题时自动生成 slug。

<div class="form-group">
<label for="name">Title of News</label>
<input type="text" class="form-control" id="name" name="name"
placeholder="Enter your title of news"
value="@if(isset($news->name)){{ old('name', $news->name) }}@else{{old('name')}}@endif">
</div>
<div class="form-group">
<label for="slug">Slug</label>
<input type="text" class="form-control" id="slug" name="slug"
placeholder="slug"
{{!! isFieldSlugAutoGenerator($dataType, $dataTypeContent, "slug") !!}}
value="@if(isset($news->name)){{ str_slug($news->name, '-') }}@endif">
</div>
<script>
$('document').ready(function () {
$('#slug').slugify();
});
</script>

问题是:

  1. 当我在Title of news中输入文本时,它不会实时更改。

  2. 因为它不会实时更改,所以它不能正确保存 slug。

例:

当我输入新闻Title字段时:Apple iPhone 7->单击按钮保存。这些字段slug不包含任何值。

接下来,我将新闻Title更改为Apple have plan release IOS 11->单击按钮保存。数据库中slug字段更改为Apple iPhone 7

您的控制器:

function store(Request $request) {
$this->validate($request, [
'title' => 'required'
]);
$news = News::create($request->all());
$news->slug = str_slug($request->title, '-');
$news->save();
return redirect()->back();
}

您的观点 :

<div class="form-group">
<label for="name">Title of News</label>
<input type="text" class="form-control" id="name" name="name"
placeholder="Enter your title of news"
value="@if(isset($news->name)){{ old('name', $news->name) }}@else{{old('name')}}@endif">
</div>
<p>The slug will be <span id="slug"></span></p>
<script>
$('document').ready(function () {
$(document).on('change', 'input#name', function() {
var slug = slugify($(this).val());
$('span#slug').text(slug);
});
});
function slugify(text)
{
return text.toString().toLowerCase()
.replace(/s+/g, '-')           // Replace spaces with -
.replace(/[^w-]+/g, '')       // Remove all non-word chars
.replace(/--+/g, '-')         // Replace multiple - with single -
.replace(/^-+/, '')             // Trim - from start of text
.replace(/-+$/, '');            // Trim - from end of text
}
</script>

我没有尝试过,但应该可以工作。您可能需要适应您的系统,但想法就在这里。
