在角度翻译服务中,正常翻译json中的插值参数效果很好。但是在嵌套的json中,插值参数不起作用。
我的JSON:
"SampleField": {
"SampleValidation": {
"MIN": "Value should not be less than {{min}}",
"MAX": "Value should not be more than {{max}}",
}
}
My Angular Code:
ngOnInit(): void {
this.translateService.get('SampleField.Validation', {
// using hard coded value just as a sample
min: 0, max: 2000
}).subscribe(translation => {
console.log(translation);
});
}
预期产出:
{
MIN: "Value should not be less than 0",
MAX: "Value should not be greater than 2000"
}
实际输出:
{
MIN: "Value should not be less than {{min}}",
MAX: "Value should not be greater than {{max}}"
}

根据source of ngx-translate插值仅适用于字符串:
export abstract class TranslateParser {
/**
* Interpolates a string to replace parameters
* "This is a {{ key }}" ==> "This is a value", with params = { key: "value" }
* @param expr
* @param params
* @returns {string}
*/
abstract interpolate(expr: string | Function, params?: any): string;
这意味着您可能需要使用键数组而不是非叶元素:
this.translateService.get([
'SampleField.Validation.MIN',
'SampleField.Validation.MAX'
], {
// using hard coded value just as a sample
min: 0, max: 2000
}).subscribe(translation => {
console.log(translation);
});

您也可以通过使用 translate
管道来执行此操作,以便您可以删除对组件的附加服务依赖项。
<p *ngIf="!item?.isRemovable">
{{'i18n.dashboard.heading'
| translate:{'TEXTTOFIND': 'STRINGTOREPLACE'} }}
</p>
只需确保您的密钥 i18n.test.key
已插入此 TEXTTOFIND
。类似于下面的内容。
"heading": "This is with the interpolated {{TEXTTOFIND}} text."
注意标题字符串中的 {{}}
,STRINGTOREPLACE
可以是您想要的任何内容。
