我在将模板变量传递给帮手时遇到问题,我得到了一个像这样的模板
{{#each row in workpage.mainStructure}}
<div class='row'>
<div class='cell cell-2'>{{i18nForecasts row.value }}</div>
{{#each cell in row.amounts}}
<div class='cell'>{{cell.format}}</div>
{{/each}}
</div>
{{/each}}
我的助手只需要记录传递的val:
Ember.Handlebars.registerHelper('i18nForecasts', function(property, options) {
var escaped = Handlebars.Utils.escapeExpression(property);
console.log(escaped);
});
问题是,我只能得到“&#39; row&#39;在字符串中而不是循环值。但是,如果我尝试用帮助器打印值,如:
{{row.value}}
打印正确的循环值。
答案 0 :(得分:2)
您希望使用registerBoundHelper
,http://emberjs.com/api/classes/Ember.Handlebars.html#method_registerBoundHelper
Ember.Handlebars.registerBoundHelper('i18nForecasts', function(property, options) {
var escaped = Handlebars.Utils.escapeExpression(property);
console.log(escaped);
});
